Not sure this has been posted or not since I hadn't read all of the GPS threads up till now since I didn't think I was having a problem... When I got the phone I wasn't using a case and the thing locked on to GPS right away. Then I purchased that clear plastic case at&t is selling in their stores. GPS was fine but I hated the case so today I returned it to get the rubber body glove one that was being sold. Tonight I tried using the GPS and suddenly it's not locking on, and when it does lock on it's way off... Anyone else experiencing this?
