Anyone suffering from this? Wanted to see if this was an OS issue with a select few or a hardware issue on my end. Every so often, not really a set time, but my touch screen just loses all touch functionality. I can still use the home button to get back to the main screen. I can even use the home button to get into 'Spotlight' but the touch functionality of typing anything or selecting any icon just dies. The only solution I have found is that I have to put it into a sleep mode and wake it back up. I just want to see if this is a 3.0 issue or if it is my phone directly? Not sure if anyone is experiencing this. Thanks!
