This happens about twice a day; when I press the sleep button and I want to use my phone again the home button and sleep button don't wake up my phone! The slide to unlock screen doesn't show up when I press any of the buttons. I have to hold the home + sleep Button to restart my phone so I can use it. Sometimes I think my phone just shuts off? I jailbroke my phone a while back but I restored it and it worked but it still has the custom carrier logo. I don't know if this has anything to do with my problem though. This happened before and after the 2.1 update. Also the "run away" deleting still happens.
