i currently have software version 6.1.2. i notice in itunes the only option is "update and restore". is there a way to maybe backup my phone now so that in the future i can restore still using 6.1.2. i know when they release a new software version i will not be able to jailbreak my device if i restore. is there anything i can do in this situation? can i install a old version of itunes and just restore the device without searching for a update? thanks in advance
