0.9.2.6 and T mobile GPRS connection?

After I put the setting info I select (new feature in this firmware,previously didnt have to choose) the desired and only connection on the list, but the wheel of Meizu misfortune keeps spinning and doesnt connect......can anyone with tmobile confirm if GPRS can be connected? if so how? below are the settings I am using:
name Tmobile
APN: epc.tmobile.com
Proxy: 216.155.165.50
Port: 9201
User/Password blank

Also other thing I observed is connection goes out every now and then with it showing 'No Service' even at places where it used to have good service before with previous firmwares!

try it without the IP Proxy settings, I think it will work then

Are you sure those settings are correct? I've been using:

APN: wap.voicestream.com
username: Leave Blank
password: Leave Blank
Proxy server: 216.155.165.050
Port: 8080

Haven't had much luck with the new build though

I haven't upgraded yet, but I use these settings.

APN: internet2.voicestream.com
Proxy: 216.155.165.50
Port: 8080
User/Password blank

Opera does not work with this FW.
I am using UCWeb, you can find it in the downloads.
Follow the instructions on the connected thread.

I use:
APN: epc.tmobile.com
username: Leave Blank
password: Leave Blank
Proxy server: 216.155.165.050
Port: 8080

epc is the latest gateway, I think it is supposed to be faster than the WAP and the Voicestream, I would suggest you guys give this a try.
For One thing, Opera DOES NOT work with this FW.

One more of JW's FW.....

Opera as in the separate application or the browser that comes with the phone? Isn't it based on that anyway?

I am still getting the wheel when I am trying to connect to GPRS after selecting tmobile. I have tried all your suggestions, thank you all for that. But, it still doesnt connect! am I missing something else?

Are any of you guys having poor reception for regular phone service with new FW than before?
