I just got my 16 gb 3g on friday and LOVE it. However, I have one problem (well, the reception isn't as good as my old phone, but I don't care). Every now and then (like 5% of the time) the screen will go black and when I push the home button it won't give me the option to slide to activate. I have to hit the on/off button a few times and just mess with it for it to give me that option again. Any suggestions? I've done all the upgrades and everything.
