I have the same problem in the Czech Republic using N900 and T-Mobile. I have tried that with E50 and have no issue to get incoming call while browsing. with N900 i become unavailable. I prefer having a call and connections dropped, otherwise I can,t be online..

Reading this thread I cannot figurde out why is that? Why one nokia phone can handle the situation and N900 cannot? On the same network.. Has anybodz got insight deep enough to explain please?
