Today we are going to cover how to successfully downgrade the iPhone from OS 4 beta (iPhone 4.0) back to iPhone 3.1.3. This can be done pretty easily a majority of the time, but at times, things go downhill, like DFU loops, errors, etc.. We will cover these scenarios right now and hopefully get a lot of people where they need to be. I’ll show you two ways to downgrade, through XCode (Mac only) and through iTunes (Mac and PC).
And as always, if you are even a little scared you may mess up your phone during this process, stop right now. What you do to your phone is always on you. These guides are there for your convenience, but we hold no responsibility for any bricked iDevices of any kind.
If that didn’t scare the pants off of you, hit the jump for screenshots, a written walk-through, and a video!
First of all, we need to differentiate between firmware and a baseband as a lot of people seem to get those confused. Firmware is the actual software your phone is running, which in most cases can be downgraded easily. A baseband however can NOT be downgraded as easy. This is part of what makes a phone unlockable (when the baseband is cracked).
Currently, iPhone firmware 3.1.3 and above can not be unlocked as the baseband version changed. So if you are trying to downgrade in order to get your unlock back, don’t bother with this process. Your baseband will currently remain at the 4.0 baseband. Even when you downgrade successfully, your baseband will remain the same, ruining your chances at having your unlock back.
What I’m getting at here is, do not downgrade in hopes of getting an unlock back. If you’ve installed 3.1.3 and higher, there is no unlock released. The only way you can unlock 3.1.3 is to have an older bootrom that was not upgraded (meaning you upgraded to 3.1.3 from a custom firmware ipsw, not the official 3.1.3).
The easiest way to downgrade is going to be to go through XCode on a Mac. If you’re just going through XCode, simply choose 3.1.3 from your available firmwares, and voila, your phone will restore. If you are a licensed dev, you should have no problem going this route. No errors, nothing. You will not need the packages listed above (at least you shouldn’t). Open XCode and go to Organizer…
Then choose 3.1.3…
If you do get stuck in a DFU loop or get an error, jump down to the iTunes directions and continue from there (typically error 1015 or a DFU loop, which is where you need iRecovery – covered below and in video). I did not include an XCode walkthrough in the video as it’s extremely simple and painless if done correctly.
Even though I am covering a PC downgrade, you should NEVER ever install a beta OS through a PC. That is not the way they were meant to be installed. Betas should NEVER be installed through iTunes, always through XCode on a Mac. Especially with 4.0. The file system changed and iTunes will install the old way, creating crashes and all kinds of other nastiness. Even though I am giving instructions for PC downgrade, I have no way to test them, if there are issues, please let me know so I can correct them.
Alright, now on to what you’ll need to have beforehand -
Here is what you need to download to your computer (to your desktop is easiest):
After you have downloaded the files above, install libusb and iRecovery (PC, you don’t install iRecovery, you run it through command prompt). Then plug in your iPhone. Open iTunes and hold down alt/option and click restore (ctrl click on a PC). Now navigate to where you saved your firmware like below (I have a folder on my desktop called iPhone firmwares).
Wait for your phone to go through the restore process (I would normally of told you to backup before doing any of this, but as 4.0 does not support backups yet, that isn’t possible. Hopefully you backed up your data before 4.0 so you can restore from that).
Your phone will not complete the downgrade, it will give you an error like below, that’s OK.
Next, open iRecovery. There are 2 versions of iRecovery. One you have to manually enter commands, the other, fast version is a button click. So for Mac users, open the faster iRecovery and click the button. iRecovery will reboot your phone and you “should” be done and able to sync and restore like normal through iTunes (you are done if you have a screen showing “Slide for Emergency”, if you still have “Connect to iTunes”, skip to the section titled “Still Stuck”). For PCs who need to enter commands into your command prompt, type the commands in this order:
Here is what you don’t want (but may get)…
When I decided to downgrade, my phone was stuck in a hopeless loop of DFU fail. I found a way around this with blackra1n.
First, download blackra1n to your computer. Launch it, and click “make it ra1n”. Wait about 30 seconds, your screen should be black but not off.
UNPLUG your phone and hard reboot it. When it comes back on, you should now have “Slide for Emergency” and be able to sync like normal. blackra1n will not jailbreak your phone, so if you want a Jailbreak, use Spirit afterwards (see my Spirit Jailbreak for iPhone 3.1.3 walkthrough). But it will get your phone out of DFU mode.
That’s it!
Just a side not: Anytime you restore you may have to repeat this process as a clean restore may still fail (at least until 4.0 official drops and you upgrade to that). Forcing your iPhone out of DFU mode can cause restores to act funky, so just save these steps for further reference. You should now be able to backup and sync like normal though.

We have some good news for those of you who are AT&T customers as it appears the carrier is rolling back upgrade eligibility dates for early adopters of last years iPhone 3GS. I have been keeping an eye on my upgrade date online for the past two weeks waiting for it to change from 11/20 with no luck just yet but a MobileCrunch reader has noticed a change to their account.
“Not sure if anyone [..] has noticed this same thing, but my Upgrade Eligibility date on my AT&T account switched from 11/21 to 6/21 in the last day or so. I bought a 3GS on launch day last year, and my upgrade date read 11/21 since then. A few other folks in my office have noticed the same changes happening to their accounts as well.”
Could Monday June 21st be the actual release date of the next iPhone? We are leaning towards no considering his original update was 11/21 while mine is 11/20 and based off that assumption, my upgrade date should change to 6/20 which falls on a Sunday. All of the speculation will come to an end at WWDC in the beginning of June. Until then, check your accounts to see if any changes have been made and let us know in the comments below!

To all you guitarists out there, we know you're incredibly particular about tone when it comes to your axe and the boutique pedals you play it through. But lets be honest, every now and again it can be a little tiresome lugging that oversized pedal board, and your vintage amp, through the underground for that one-off "favour for a friend" gig. Especially when the venue won't be able to handle your tone anyway (as apposed to that sell out rockin' show you did with the guys the night before).Continue reading Count The Beats: IK Multimedia announces Amplitube iRig for the iPhone

Fresh off NPD's latest Mobile Phone Track report claiming that Android has leapfrogged the iPhone in US sales, Apple is commenting on the numbers -- and as you might expect, they're not exactly taking a congratulatory tone with Google. Speaking to AllThingsD's John Paczkowski, Cupertino had this to say:The factual accuracy of Apple's words here can't really be disputed, but as Paczkowski notes, the context can: lumping the iPod touch into this equation isn't really fair, since NPD's report is about smartphones, not mobile operating systems (which would've let devices like non-phone Android MIDs into the picture). Besides, this is about the US market in the first quarter of 2010, not global sales, nor is it about Apple's development pipeline. In other words, Apple's not disputing NPD's report here -- rather, they're simply trying to change the subject, as any properly-trained PR department would. There's no question Android still has an uphill battle to dominate market (and mind) share the world over, but the odds that it outsold the iPhone in the US in Q1 remain very real."This is a very limited report on 150,000 US consumers responding to an online survey and does not account for the more than 85 million iPhone and iPod touch customers worldwide. IDC figures show that iPhone has 16.1 percent of the smartphone market and growing, far outselling Android on a worldwide basis. We had a record quarter with iPhone sales growing by 131 percent and with our new iPhone OS 4.0 software coming this summer, we see no signs of the competition catching up anytime soon."

Gowalla for iPhone is a social app from some fine folks in Austin, TX that allows you to check-in to locations, see where your friends are checking-in, collect items and complete trips. For those of you not familiar with the whole “check-in” craze, the idea is you travel around town, land at a “spot” such as the movie theater, gas station or restaurant, and then tap the Check-in button. When you do this a couple things happen:
You can…
There are some great social aspects to Gowalla, but let’s first talk about items. After installing Gowalla on the iPhone, you receive three items. You can keep and cheris these items in a vault, never to be used, or you can swap for other items at Spots when you check in. You are also randomly given items when you check into locations. I found myself without an item for a few weeks, but fear not, I received two items randomly twice in a day! Other then exchanging an item at a Spot, you can leave an item at that location if now one has. This will give you “founder” status.
What I particularly love about Gowalla compared to it’s competition, is that it is not focused on mayorships or point leaderboards. I tend to think I go a out a fair amount and explore the city with my family, but there are some people that go out even more than I do and I will never catch up to them in points. Gowalla’s main attraction for me is the item collection feature.
For those adventurous types, there are trips. Trips are not built into the iPhone but are on the website. When you follow these trips, you earn a special badge. For example, I will be visiting Chicago and I am going to try to complete the Chicago trip.
To find friends to share with, Gowalla gives you some tools to can scan your address book, Facebook, Twitter, and Gmail, and you can always find by name.
All of this is rendered with beautiful icons and graphics that really allows you to enjoy the experience of the application. The only major detractor for me is that the application is still a little slow, but boy is it pretty…
Gowalla is available now in the App Store for free [Free- iTunes Link]
