guys, i am planning to restore my iphone thru itune and then JB using jailbreakme.com But, what i have noticed, earlier i used sn0wbreze to JB my iphone4, with that there was Hactivation option inbuilt in sn0wbreez. Now if i restore my iphone4 thru itune, how would i hactivate it ? i am tmobile customer. and when i bought iphone4 from one of my friend, at that time it wasnt activated. please help.
