Hi, I've upgraded to a 6+ but still plan to keep my old 5. Would like to jailbreak the 5 to mess around with/use it essentially as an ipod. I was wondering if any problems/issues could come up trying to backup and jailbreak an old phone? Is there anything I should be aware of or any steps I should take on the 5, such as trying off imessage, etc. before doing the jailbrake? Mainly just want to make sure nothing on the 6+ will change or be affected at all. Any tips/help would be very much appreciated! Thanks!
