Hello, After I checked some of the features of jailbreaking iOS devices, I decider to go for it. Unfortunaly, I upgraded to 6.1.3. So, the only way to jailbreak is to go back to 6.1.2. I downloaded the IPSW file, made a full backup on my computer, shift-clicked "Check for updates" and I selected the file. After a few moments, it tells me it can't be updated. So my only way now is to fully restore my iPod Touch with 6.1.2. However, if I do a full backup on my computer, if I select when setting up my iPod: "Restore from an iTunes backup", will it be exactly how it was when I backed up all my data? Also, I know a guy in school that he jailbroken his iPod Touch 4G and he made so he could have different unlock types, like instead of the basic 4-digit code, he can get something like the Android style (with 9 circles you have to correctly link) and that he could play a few notes on a virtual piano keyboard. How do I get theses?
