Hi! I have a question about my iPAD. iT'S 2 YEARS OLD AND IT WORKED WITHOUT ANY PROBLEMS UNTIL YESTERDAY. when i was using multtasking gesture to exit the screen suddenly froze. and what is strange i can see if i have WI-FI on and I can see clock - and battery percentage. but the rest of the screen doesn't respond. i tried to connect with itunes but i need to vertificate and i can't do that cause screen isn't working. Any suggestions about what is happening to it? i also uploaded a photo of current situation. tnx for your answers.
