Data no longer works after updating to 3.0 on 3G

[lambo]

Hey, I've been using T-Mobile for almost a year now on my 3G and everything has been great. I've been using the T-Zones, but after I updated my 3G to 3.0 and entered in "epc.tmobile.com" in the APN settings, it no longer works.

When using an app that requires internet, it tries to load but just says there was an error and it cannot connect. It does not say, however, that I don't have an internet plan, which is what happens when I leave the APN blank.

Also I'm having trouble with MMS. I entered in all the correct information and managed to get the little camera to appear, but when I send a picture, it attempts to send but fails in the end.

Thanks!

Do a search for other APNs. Sorry I don't have it on hand but that should work. And don't forget to turn off 3g in the settings.

I've already tried internet2.voicestream.com and 3G is off.

EDIT: It now randomly works with epc.tmobile.com although MMS still does not work.
