Cannot use any Pocket Pc SMS application to retrieve SMS from 6630. Tried SMS manager and Simple SMS. SMS are sending ok, but retrieving does not work. Pocket Phone Tools does not work at all.
Any experience or idea?

I emailed the company that does simpleSMS since i had the same problem with a 6600.
Apparently, symbian phones store the SMS messages in their own database that cannot be accessed by SMS apps.
Not sure if this is a general problem or if it's being addressed.
