GPS not working with DTAC (Thailand) APN

[amitsch]

Hello,

i just came back from a short holiday in Malaysia and had to realise that my GPS on my SGS2 is not working anymore.
Not even the icon in the task bar is showing so its not just the fix.

I found out that it is working if i put any other SIM card in it than a DTAC SIM and its also working if i delete the APNs for internet and MMS and reboot.
But then the GPS works but i cant connect to the internet of course. as soo as i enter the APNs (either by hand or automaticly) the GPS stops working again...

Before i went to Malaysia everything worked fine...

Just relised it is working with the APNs but not if there is a DAta Connection.... Clicked the home Buuton so that the screen switched on and i could see the GPS Icon but as soon as i entered my screenlock pin and the Data Connection was activated, the GPS went OFF...

Any clues???!!! I am really desperate here...

Can anyone help me please!!!???
