Okay guys, I don't come around this forum unless I'm having trouble with my phone. I updated my phone a few days ago maybe three with software I got from tmobile's site. Everything went through fine, but now I can't send MMS messages nor receive them.
It says:
Could not retrieve content try again later.
So I open the menu and click retrieve and the little screen saying retrieve appears but nothing loads.

Any help will be greatly appreciated.

I know this is not going to help but I have hear that T-Mobile is having problems with MMS Messages. I will get some 2 to 3 days after they were sent. Sorry I couldn't help more.

Oh, well the message finally loads a few days later or you receive it? Because mine arrives immediatly, just won't display it.

edit

I tried sending the MMS from the blackberry to myself and I get an x next to the message and it says it failed to send.

sounds like t-mobile have cut off your mms/gprs capabilitys....
or they are having problems with their MMS system which is very common.

I presume you can still make calls / txts / visit webpages?
