Cingular 8525 Help

[gachamp2]

I just bought the Cingular 8525 unlocked phone, and I'm using it on T-mobile's network, I can make calls, and text msgs, but not send or receive MMS. I've tried setting up the connections and MMS connection to use a GPRS but can't get it to go through. If anyone could help me out with this, I'd greatly appreciate it. I even tried the T-mobile Data Connectivity site for phones like the HTC 100/Cingular 8525. If someone would be so kind to walk me through the process I'd greatly appreciate it.

I've tried for example:
I have made a connection named T-mobile and under modem I have GPRS selected and for the number a Access Point named wap.voicestream.com for user name, password and domain are all left blank. I have nothing selected under VPN or Proxy Settings tabs.

Under my MMS settings, I have the server name set as T-Zones, the gateway at 216.155.165.050, the port number is 8080 and the server addy is http://216.155.174.84/servlets/mms and it is selected to connect via the T-Mobile modem connection that I set up in the previous paragraph. Any help would be greatly appreciated! Post here or email me directly at Gachamp3@aol.com
