i have a HTC Desire with Cyanogenmod 7.2.0.1. Also tried MIUI 2.4.6

to your questions:

1. yes it is the same for both: message connecting then unexpected interrupt.

2. i have TrustGo as protection app, i alsoe deinstalled the app, reboot the phone and still the same issue

3. i tried with android and also with ffmpeg engine both have the same issue

like mentioned before these are the only stations that i tried that don't work with mobile connection, meverything is fine when using wlan. when using wlan both engines work fine and also with trust go installed and enabled
