Eqpt: Original OLD iPad, 64mb.
I have same problem. Although my crashes have now developed a pattern. (Example: editing a listing on eBay always causes crashing at exactly same spot, over and over.)
I have spoken to "AppleCare" numerous times. Everything they seems to help at the time, but soon after I encounter new websites that causes new crashes.
I finally took my iPad to APPLE STORE and gav the problem to a GENIUS to solve. He prayed over my Pad, spoke some technical mumbo jumbo, went to the BACK ROOM, reformatted my iPad and declared my AppleCare Coverage void because I had dented the aluminum back when dropped on carpet.
I guess the definition of AppleCare is: You have coverage until something goes wrong, than we find a scratch, or dent and declare your coverage VOID because you are to be punished for not being perfect.
Problem unsolved!
