Upgrade to iOS 7 Today

Were you excited about last weeks preview of the newly skinned iOS 7 at WWDC 2013?  Are you itching to get your hands on iOS 7 now rather than wait until mid-September?  Well, you can, if you desire, download the beta preview like developers can, without jailbreak, without paying to register your UDID.

To do the upgrade is quite easy, just follow these simple steps and you’ll have it up and running in no time.

One caveat:

This is the first beta release, so it’s a bit buggy.  If you rely heavily on your iPhone, and you absolutely can’t live with a glitchy version of iOS, then I recommend that you don’t perform this upgrade.  Since installing iOS 7 it’s rebooted on me several times and I haven’t even had it up and running for 24 hours yet.  So, fair warning, and if your brick your phone, it’s on you, not me.  Besides, if the upgrade doesn’t work, you can always restore to your last backup which will downgrade you back to 6.1.x.

Ok, enough with the disclaimers and on to the upgrade (which is actually really simple).

1. Go to settings… general.. software update and be sure your device says it’s up to date.

2. In iTunes, select Help…Check for updates, and make sure you’re running the latest version of iTunes.

3.Go to iModZone and download the proper .ipsw for your device.  You can just save it to the desktop for easy access. There is a different .ipsw for iPhone 4, 4S, and 5, and there’s 2 versions for each, one for GSM and one for CDMA.  Getting the right version of iOS 7 for your device is important, your phone will not work unless you get the right one.  Verizon and Sprint users need the CMDA version and AT&T and T-Mobile users need the GSM version.  Aside from that, pick the one for your model (4, 4S or 5).

4. Connect your phone to your computer via the USB cable, and with iTunes open, select the device in the sidebar.  The sidebar is hidden in newer versions of iTunes, so if it’s not there, select <CTRL>+S to show the sidebar.  With iPhone selected, the pane on the right has the Check for Updates and Restore buttons.  Hold Shift (Option on Mac), and left click the check for updates button.  Instead of going to the Internet to check for an iOS update, a file open dialog window will appear.  Navigate to the .ipsw you downloaded from iModZone and select it, then click “Open”.  iTunes will then state that this action will update you device to iOS 7.  Click “OK”.

5. Done

That’s it… let it go and after the phone reboots, you’ll be in iOS 7.
