hello there, im new with android, I have a coby, I like it so far, but he only thing it is doing if i am on e-mail. or on the web, it will someime freeze up, then i can"t do anything with it, I can"t turn it off or i can not turn it back on. I have to wait till the battery dies out. then I will plug it back in then it will work again. anyone else have a problem like this, Thanks
