mine never hang, however last month before JBed my iPad 2, I was too rajin and create folder to arrange my games icon and apps separately, after that when I tried to sync my iPad 2 with iTunes, it detected some problem and advise for a restore to be done.

done a restore, it took like forever, and my Other folder size is more than 12gb. I decided to reset back my iPad 2 and since then there is no problem, it's been around 3 weeks now after I JBed there is no problem at all. it works flawlessly. at the moment I only install SBSettings from Cydia, for easy access of Wifi and to reboot my iPad 2 :0
