Thanks a lot for your help, yes when its idle the 2G, 3G or WLAN are still on and it shows online, everything works as usual, I get calls, IM, SMS, etc. when idle.

with
"could you try & made a STOCK standard install (still with your personal data, of course, but WITHOUT any extras-testing, leave alone extras-dev SWs...)
even better, not even extras stuff"

Thanks again
