    I had the same issue for the longest time. I finally messed around and combined a couple of techniques to get it to work. I have both a 3g and 3gs and it works on both.

    first I searched cydia for t-mobile US - Prepaid (from ModMyi repository) [download and install]

    Then set my "Network" settings under "Cellular Data Network" to the following:

    Username (blank)
    Password (blank)

    Username (blank)
    Password (blank)
    MMS Proxy
    MMS Max Message Size 1048576
    MMS UA Prof URL

    not sure if needed but i powered down and then back up. I was able to send and receive pictures messages from other iphones (any network) and also other phones (i.e. gravity 2).

    Default Can't receive MMS, Can send MMS. Please HELP!
    I used Spirit jailbreak and Unlocked my iphone 3GS version 3.1.3 firmware 05.12.01.
    Also there is no longer a T-Mobile US - Postpaid package to download from Cydia when trying to search "legacy".

    My Iphone's cellular data network settings are set to:

    Cellular Data

    MMS Proxy:
    MMS Max Message Size: 1048576
    MMS UA Prof URL: http//

    I can send mms but cannot receive mms. i just get message "the media content was not included due to a picture resolution or messsage size restriction". Can anyone advise??? I've also tried all the different cellular data settings listed by different users in this and multiple threads. Can anyone help???

    i do not want to upgrade to version 4.0.1 (nor to any version higher than my current 3.1.3 because it will lock it up for at&t only). since i already have mine jailbroken and unlocked, i just need to figure out the settings to be able to recieve mms. Please advise. Thanks!
