No Internet in Browser and EDGE failure

[alexnaha]

Hello, I just bought a Blackberry bold 9650, originally was for Sprint, but now is unlocked and I'm trying to use it with my T-MOBILE SIM.
The emails are working good, the whatsAPP is working good, BUT, when I'm trying to get into the browser I'm having this message; BROWSING IVER THE CELLULAR NETWORK IS NOT INCLUDED AS PART OF YOUR CURRENT SERVICE PLAN. TO BROWSE THE WEB YOU MUST USE WI-FI OR CONTACT YOUR SERVICE PLAN PROVIDER.
I already did this and TMOBILE says everything is normal, Also the EDGE word is going on and off UPPERCASE and LOWERCASE.
I just contact another representative of Tmobile and he told me that I need to reach SPRINT and tell them to send me the Service Books for SPRINT, please someone can help me with this? I don't have a clue of what could it be.
Thanks!!

A quick search of this 9650 forum using (sprint, 9650, tmobile) comes up with this.
