T-Mobile iPhone - NEED MMS Fix.

[rivenagares]

so i just realized that my Gevey SIM hacked iPhone wasn't receiving MMS messages. Instead i get this message,

The media content was no included due to a picture resolution or message size restriction.

this is regardless of what is actually sent. now i've tried the various APN settings i found on the web and i'm baffled as to why it won't work. my phone is NOT jailbroken since i have the Gevey SIM.

i am looking for a solution that does not involve Cydia.
