iOS 5 beta 3

well.you just need to click on the restore button with the shift if you have a pc!!Then choose the .ipsw file and that's it it will restore to 4.3.3

 

no you'll need the itunes 10.5 beta 3. because it already has the ios 5 beta 3 and that version workd only with this version of itunes.So you'll need the itunes 10.5 beta 3 .But it may still work with the itunes 10.3 but it's better to do it with the latest one (10.5 beta 3) it's guarantee

 

Whoa the phone came with iOS 5 beta 3? That's rare dude :O

But if you really want to downgrade, just put the phone into DFU mode, hook it up to iTunes, and restore it. It should go back to factory settings. Or just get the 4.3.3 ipsw file and hold SHIFT then click Restore and point to 4.3.3

 

1. Downgrade iTunes by doing a clean install (try not to delete old library as new library is not recognized by old one so copy it first)
2. Download the ipsw for 4.3.3
3. Put iPhone in DFU mode (too lazy to type out how so google it)
4. Let iTunes recognize DFU mode
5. Hit restore and choose latest 4.3.3 backup if you want
6. You should be done
