What to do about iOS 5 error codes
>By James Lenhart
Alright, so you’ve been waiting around for the last couple days/weeks/years only to be disappointed by some error code preventing you from successfully installing iOS 5 on your iDevices. Well here’s the good news — you’re not alone. In fact, many people just like you are freekin’ out because iOS 5 isn’t installing, and the culprit? A quick look at Apple’s website and we can see that error codes between 3000-3999 are most likely indicating that Apple’s servers are being bombarded by the world. To be more technical, iTunes wasn’t able to connect to gs.apple.com over ports 80 and 443.
Basically, you/we are going to have to wait it out. Both myself and Chris West have not been able to install iOS 5 successfully. He’s on AT&T with an iPhone 3GS (soon to be 4S I believe..), and I’m on Verizon Wireless with an iPhone 4.
UPDATE: I was able to install iOS 5 with no errors manually. Full instructions can be found here.
If you’ve tried installing iOS 5 multiple times and are running out of disk space to store the backup files — try deleting them.
Here’s were they’re stored depending on OS:
Mac OS: ~/Library/Application Support/MobileSync/Backup
Windows XP: %AppData%\Apple Computer\MobileSync\Backup
Windows Vista: %AppData%\Roaming\Apple Computer\MobileSync\Backup
Windows 7: %AppData%\Roaming\Apple Computer\MobileSync\Backup
We take no responsibility if you screw things up — this is your call. Backups are made up of hundreds of files stored within one cryptically named folder. Deleting the folder will remove the backup.
