i have an iphone 4 and it's jailbroken with cydia for tmobile, 4.01.10; 4.3.5 i tried to reset all settings in order to get rid of all of my contacts/pictures/and music and now it's stuck on the screen where it's a black screen with a little white "processing" icon or whatever it is that is showing that it's in process. it has stayed like this for over an hour now and i'm sure there's something wrong with it. holding the power and home button down doesn't do anything, plugging it into itunes doesn't do anything--it doesnt even recognize the device! What do i do?!!! please help!
