Habs fixed!
but since I do not want to delete the thread and others still want to be a help here is the solution:
http://www.go-android.de/forum/android-provider/bildmobil-internet-und-mms-einstellungen-(apn)-bspw-mit-htc-magic/
because you'd have to simply 'nen second APN for MMS set up, activate, download the MMS and have the bunny hops :)
