How to enable internet and MMS on the iPhone 3.1.2 with the carrier T-mobile.

this is the only method that has worked for me in order to enable MMS on the iPhone with Tmobile; however for the internet you can use : epc.tmobile.com and it should work as well, but for MMS you should get the information in my video.

Note: this works only for iPhones that have a Data Plan with tmobile.
