I sold my G1 week ago ( i had 2) now there buyer tells me that the touch screen doesn't working any more ,but the thing is that he tells me that he took the G1 to T-mobile retail store and they told him that the touch screen had stop working 2days before the day that i sold the phone (but i was working when i sold it i was using the phone) now my question is that is this even possible ? can they pull up this kind of information ? the device is running the latest CM rom ?
