I only have one issue with my TB, but its a pretty big one. I travel a lot to different cities. When I land, it takes my GPS a minimum of 45 minutes before I'm located. I get the dreaded "Searching for GPS"... It chews up battery life. However, once I'm located, I'm good for as long as I'm in that city. I have tried shutting the phone down and bringing it up, I have tried apps like GPS Status and GPS Fix. GPS Status will show I'm locked onto 9 satellites, but it won't hook me up with the GPS. My local Verizon "expert" said I should dial *228. I've done that and gotten a message that says "A Verizon Wireless SIM card has activated your service and updated your phones roaming capabilities". Nothing. When I arrive back home, it take at least 45 minutes to connect. Sorry, so long, does anyone have any definitive suggestions?
