Anyone having issues with GPS? I purchased the phone yesterday and it is nice (very fast & the screen is incredible). Unfortunately, I tried to use the GPS today and it took approximatley 60+ seconds to lock. I tried it later in the house and it is having difficulty finding satellites, where my wife's Photon 4G locks within 5 seconds (some case 5 to 7 satellites). Please tell me I have a defetive unit. I will not go through another Epic 4G GPS disaster.
