i am selling my 2g iphone version 2.1 , the buyer is picking it up tomorrow, so i thought i should delete everything from the iphone, so after searching around, i went to Settings->General->Reset->Erase All Content and Settings. It's took a while, after it finished, the iphone restarted itself, and i got stuck at the pineapple logo after, and it just keep on restarting the phone itself, anyone tell me what can i do now??
