[nickname]

Okey straight to the point
My device: BB 8320 curve titanium TMOBILE NETWORK

1/ I cancelled my BB data plan 2 days ago. so EDGE immediately becomes "edge". UMA becomes "uma"
2/ I have Dlink WBR-1310. I am able to CONNECT my BB to ROUTER with no problem. SSID okey, no encryption

This is what I KNOW
after connecting with the ROUTER, my BB screen shows "uma" (lowercase), I AM ABLE to make calls, send txt BUT I CANNOT BROWSE internet

This is what I have TRIED to troubleshoot
1/ WIFI diagnostic test - done successful
2/ PIN my wifi-gateway - done successful
3/ Change my router channels and configuration
4/ Pull out the battery on BB
5/ CALL 611 tmobile with NO HELP
6/ DATA plan is on, default browser configu: internet browser, default MDS: internet browser, and
Default WAP browesr: t-zones <-- I only have one option

Okey, so now I am hopelesssly trying to figureout what to do. ALL I NEED is to beable to BROWSE internet on my BB while I'm at home.
btw, what is Blackberry Feature Enabler ????

PLEASE HELP.....................

3/ they reset something ...u go online and check for connection - it works.
4/ pull out the battery and your uma -> UMA
