So I updated my 2G 8gig iPhone with the latest software awhile ago and have been experiencing issues with the keyboard and bottom part of the screen in general. It has gotten progressively worse, as now I cannot respond to a text message because the bottom part of the screen is unresponsive and when in safari I can't put spaces in searches, same thing in maps, etc. I tried doing a hard reset and a complete restore to no avail, aside from taking it into the store, what are some other things I could try to fix it? (Right now I will accept throwing it against a wall as a reasonable response)
