I have had my IPhone 3G for less than 2 weeks. It was great when I got it. But now all these little problems are popping up. 1. Random letters are typed. When I text, type in the address bar, or use the keyboard at any time, I can even NOT be touching the keyboard at all, and random letters are typed. If I try to type the word "farm" for example, often it will come out as ffqaNmro. One time I was viewing a friend's facebook page and it wrote on her wall! It wrote the letter "p" and submitted it. I had to delete it and then actually write something on her wall to cover it up! 2. The page changes on its own. I can be texting and it will take me out of the text page altogether. Lately it likes to open up that Stock application on its own... I have never even touched that one on my own. 3. When I click on any of my apps that I added myself, it takes me there for 1second and then immediately closes the application. This is a recent development. 4. The screen goes black and stays black during a call. It used to be that when I pulled the phone away from my face, it would light up with options to view the keypad, turn the speakerphone on, end the call, etc. Now, there is nothing you can do to see these options. The phone won't do anything... Not even the locked screen will come up without pushing the button on the top like ten times. This was problematic especially when I tried to call a number that required me to press "0" for the operator -- I couldn't because I couldn't access the keypad. I have tried doing a hard reboot, plugging it in to the computer to check for updates, and I even reformatted the thing! Wiped it clean! I EVEN took it in to the AT&T store... they told me they didn't know what was wrong with it.
