I had a purple line going across my screen and I read somewhere it is a hardware issue. I was going to bring it to Apple first thing when I return from vacation. Today a thicker blue line started flickering to the left of my screen and it totally froze. I tried turning it off and it did not work. The battery eventually died. I plugged it in and iTunes does not recognize it. I have NOT tried a hard reset yet because I downloaded apps here that I never synched to my computer. Will I loose these apps? If it were one App or 2 I would not mind but I spent at least 25 dollars since being on vacation. Any help will be greatly appreciated!!! Thank yoU!
