HELP T-MOBILE US MMS Problem on HTC HERO

[woodhi13]

OK so I don't have a Data plan Nor do I plan to purchase one because I am always around Wi-Fi. I have Unlimited SMS and MMS. However, Ever since I updated the Hero to the New Official HTC Hero Firmware ROM Upgrade for HTC Hero_2.73.405.5 I have been Unable to Send MMS. I can Receive MMS just fine. I have tried Mutiple APN's for tmobile and was even on the phone with there tech. Support for an hour or more just for him to refer me to Google Forums.

My current APN is

Name: T-Mobile US
APN: epc.tmobile.com
Proxy: <not set>
Port: <not set>
Username: <not set>
Password: <not set>
Server: <not set>
MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc
MMS Proxy: <not set>
MMS Port: <not set>
MMS Protocol: WAP 2.0 (don't know if this is important)
MCC: 310
MNC: 260
APN Type: (leave this blank)

However I Also used

Name: T-Mobile US
APN: epc.tmobile.com
Proxy: 216.155.165.050
Port: 8080
Username: <not set>
Password: <not set>
Server: <not set>
MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc
MMS Proxy: 216.155.165.050
MMS Port: 8080
MMS Protocol: WAP 2.0 (don't know if this is important)
MCC: 310
MNC: 260
APN Type: (leave this blank)

Both of them Allowed me to Receive MMS just not send it. Any Ideas??

Unfortunately, after a little research, your stuck. It is what it is. It's the difference in Networks. The U.K. and U.S. are exactly alike, but completely different. Same issues apply to U.K. Hero on AT&T in U.S.. :(
