1. How to I ugrade my iPhone 4 (ios 4.1) to ios 6.1.2 instead of 6.1.3? Some say download the ios 6.1.2 firmware first and after that open iTunes then press shift + restore and choose the firmware. Will that work for my current ios 4? Do I need to enter DFU mode first?
2. I have an another iPhone 4 which has been updated to ios 6.1.3 and I do not save any SSH using tinyumbrella or other tools for degrading. Can I restore the iPhone back to the factory firmware (ios 4) using iTunes and jailbreak it?
3. Can I transfer all the installed apps or cydia tweaks from a jailbroken iPhone to another jailbroken iPhone? Can i - Backup iPhone A first using itunes and after that connect iPhone B and restore by using the backup of iPhone A. It seems won't work. Lol
