unlocked V551 for T-mo

My Motorola V551 was recently unlocked and now I use it on T-mo. everything is ok, except that I can’t get onto internet. Every time I try it says Network not found. Any suggestions what settings I need to change? It was Cingular’s phone before

I got the same problem with the same phone. You need to have your phone configur to use it on T-mobile web. All you have to do is go to TMOBILE DATA Configurator on t-mo site and they'll send you text messages, which will automatically configure your phone. It takes only a few minutes.

Is there a manuel way of doing this? I have a cingular phone that isnt normally supported by Tmobile. So Im not sure what to do.
