T-Mobile iphone working MMS but Incoming unviewable

hello,

i recently downloaded 3.0, jailbroken the iphone and unlocked it using redsnow.

i input the settings for the mms and data and all goes well, when i send out pictures, it comes out perfect for the receivers but when i am receiving for incoming, its all blurred. What i am thinking is its the user agent of the phone that tmobile is unreconizable so is there a way to change the user agent of the phone (not the browser) or is that not it? thanks.

are you sure it's 2G iphone you have, and if it's, please tell me where to input MMS info
thanks

you have to update the carrier file in order to see the settings to input.. search for the tmobile carrier file for iphone.
