i have been using my n900 on tmobile since i got it in early December, and it has been great. I updated the other day to firmware I believe it was 44.2, and it became hit or miss. It shows 3G or 3.5 all the time, but web pages won't load. I get an error screen, and have to retry several times. Other times it works great, and my 3G feels almost as fast as my home wi-fi connection. I was hoping this would be fixed with firmware 51.1, but today has been more of the same. I was originally usung inernet2.voicestream.com, but switched to apc.tmobile.com to see if that would help. Is anyone else having this issue? I am on tmo usa in the Orlando, Florida area.
