I suffer form these dropped call problems that many others with the same one operator in Sweden. We are trying to track it down since everything works perfect with every other operator then this specific one.
Every time I get a dropped call the baseband have crashed and restarts.

My problem is that when I launches the FieldTest to have a look it freezes and crashes everytime. The times it do stay alive for a few secs is when I have an actve edge connection and are transfering data - like checking mail etc.

Anyone with a clue on what is going on and how to solve it?
