My son in law just arrived in the us and brought along his ipad1. It has been jb'en before using a 3.xx os if I am not mistake. No way to verify the ver cause iPad is messed up right now.... So I plug the ip1 into iTunes. Before doing that, he goes to general setting in the ip1 and hits the reset button ( kinna like erase data and settings) so ipad1 is dead after the reset. Just stays on the apple logo and don't go nowhere... I read some post and finally figure out how to restore using iTunes. So I follow instructions and when all is said and done the iPad now is stuck with the USB to iTunes logo... I've tried several times to reinstall but I get the same msg from iTunes saying the iPad Is not recognized or vaild or something to that effect. I tried everything and I'm still stuck with that invalid mag and on the iPad itself, the USB to iTunes icon... Help please....
