I apologise if this issue has been covered in previous posts/topics but I am a novice considering N900, and I have some specific questions concidering the issue. 1. My friend has a N900 that apparently disconnects!?(as has been described to me) from network when calling, otherwise works like a charm. What causes this possibly? 2. Is this problem fixable (I know the description is inadequte), by me/care and what are the costs for this possibly. 3. Any other suggestions on this, as a N9 owner just getting to know the community I would like to have a N900 but I am just trying to figure out is it feaslible to get this N900.
