I have a issue with my Sons iPad mini. I used it while my iPad was in for repair. I tried syncing it to my sons iTunes account but because I restored it and jail broke it on the latest jailbreak at the time 7.0.6. I must of linked it to my iTunes now when I try and re-sync it to his iTunes I am getting a message it can only be linked to one iTunes account and giving me the option to cancel or erase it to link it to his. If I erase it does it just wipe the data or would it restore it loosing the jailbreak.
