I'm still having issues receiving MMS's. It says "Get media content now" with some new additional info on file size, but after tapping on it, I still get the IRRITATING *ding* and nothing...
I have some good news and bad regarding the MMS settings on the HD7. The good news is that there is a fix! The 'bad' is: it requires a factory reset to apply the changes.
Just so you know, I have tried this out myself and MMS is now working 100%.
How did you debrand your phone? Just call tmobile and tell them you're taking your phone overseas? I also have a US tmobile HD7 and am having a lot of issues. Thanks
