Currently Being ModeratedNov 6, 2010 12:26 PM (in response to Mjzraz)Nevermind about it being the TomTom app. They seem to be related to having the case on. I have never seen this until I put a case on my phone a few days ago. It was just doing the problem and I took the case off and now its perfect as it's always been.Mac OS X (10.5.4), DLink Dir-655
Currently Being ModeratedDec 8, 2010 4:20 AM (in response to Mjzraz)I don't have the Tom Tom app. Restarting doesn't make a difference. I did try resetting, but not a restore. The problem still happens once every few weeks, USUALLY when I am really depending on it such as while traveling. This makes me think about usage since we are using it constantly.
At any rate, I will see if the case on or off makes a difference next time it happens. I did read about it being a possible grounding issue where the case is preventing it from grounding? Who knows. I almost got to the Apple store with it misbehaving, but as soon as I got there it was fineIphone 4, iOS 4

Currently Being ModeratedDec 19, 2010 2:29 AM (in response to Mjzraz)This may not be pertinent but I have a similar issue when connected to a cheap after-market charger.
Currently Being ModeratedDec 27, 2010 5:28 PM (in response to Andy Thornton UK)Yeah I agree with the last guy. At first I was skeptical that a charger could cause such a problem, but then I noticed that I was plugged into a charger that I don't usually use, and when I tested it I found that the moment I unplugged the charger, all of my problems went away instantly.iMac, iOS 4

No need to buy new chargers. It's a limitation of the iPhone capacitive touchscreen. The screen recognizes electrical signals from your fingers but when charging, it wobbles when touched because it is confused with electrical fields of your fingers and the charger.
When you want to use the iPhone when charging, un-ground it by touching the metal bezel with your other hand. This is easily reproducible.

Yep boxerboi, you were correct! literally as soon as I peeled back the case and touched the aluminum bezel, the problem went away. Good call man.
