Well, I live in Manhattan(NYC) and I have no problems with service I have full service everywhere on T-Mobile and all my friends in Manhattan don't have any reception problems with Sprint, T-Mobile, Verizon, Nextel, or Cingular...I do notice that a lot of my friends in Brooklyn have some reception problems. Anyways, I use my Sidekick 3 for txting, IMing on AIM and MSN, Email, and web....and the web browser can be slow sometimes on the Sk3 and plus the Sprint Treo 700p offers way more like video playback, pic msging,sound recorder,and plus I can get watch music videos, tv, listen to music, and they have EVDO which is 30x's faster than EDGE. I do like typing fast too.
So, I think I'm gonna try the Sprint Palm Treo 700p for 14 days and if I don't like it then I'll go back to my Sidekick 3.
