i guess i am somewhat fortunate with my tmobile service having been in a 12 year long relationship with att. i get 3.5 in westchester where i live as well as in tampa where i travel quite often. coming down on the train it does get a little spotty on metro north but i can live with it as it does come back as i near the city. where i do haver some deep frustratyion is with the serv ice coming back up to speed wheni can check my messages and even male a call. with my n82 on att i was able to get right back online after a dropped signal where with the n900 it seems to take a lot loinger to get a full signal for even voice to lock in. overall though i am very happy with tmobile in fact i took advantage of the free phone for my son. free plan till 2010. check it out
