Sold an ipad 1 to an acquaintance. I logged out of the my account on the ipad, I did a full wipe on itunes via my MBP, then installed 5.1 (previous OS 5.0 JB). Friend emails me today and says he tried to install some apps and my account comes up! I went into itunes on my MBP and it shows the ipad 1, I thought a full reinstall to a new OS would wipe all my info out. I did nothing other than shut the ipad 1 off when the new OS installed. Is this something we can fix through his PC or am I going to have to drive 5 hours and fix this on my MBP? Thanks!
