You can not downgrade any app. You can update, but not downgrade. There is nothing that you can do. Sorry.
One way to downgrade an iPhone 4 is to go into settings on the phone and reset it to factory settings.
JailBreak it and install UltraSn0w via cydia, if it doesnt show up add the repo: repo666.ultrasn0w.com
Not yet possible fried. However, some sources say that Applenberry is working for a new type of unlocker like GEVEY.
An iPhone 4 is an iPhone.....
I doubt if you could ! Normally, you're only able to upgrade hardware and software to a newer version. That would be like swapping your current car for an older model.
It is the 4th model of iPhone. But iPhone generations do not go from one up: 1. iPhone 2. iPhone 3G (because of 3G connection) 3. iPhone 3GS 4. iPhone 4. 5. iPhone 4S
No, they made the iPhone 4 case for a iPhone 4 not a droid.
No you both have to have an iphone 4 :)
iPhone 3GS. Then the iPhone 4 and then the iPhone 4S.
Do the iPhone 4 have ios5
Yes the iphone 4 is better so you should upgrade to the iphone 4.
The OS 8 is for the iPhone 4. The iPhone 4 is a really popular phone.
