I'm using the Motorola Droid while visiting our son here in Tustin CA. We are having very poor reception and dropped calls here. According to the coverage map we should be fine. Phone works while upstairs, but not downstairs. Is there some secret to getting coverage downstairs? My son was thinking of switching from T-Mobile to Verizon, but he's not sure now after seeing the coverage problem here in the Tustin/Irvine border area (Great Park). Appreciate any ideas...thank you. From an old senior...please teach this old dog some new tricks.
