I am an unlucky soul who can only get 1x data signal and minimal cellular signal while in my work building. I have poured over the internet looking for ways to get a decent EVDO and cellular signal coverage in my building (I get full EVDO and cell signals if I walk outside) but can't find anything definitive. I am assuming (and hoping) that this "1x" singla area is the reason I can't ever get more than 12 hours of battery life out of this device when the only thing running is direct push email to my Exchange 2003 SP2 server. Has enyone done this?
