I'm on T-Mobile USA and I can make a conference call with up to 2 other callers. If I use another phone (tested it with iPhone, E71, Blackberry 8500, 5310) I can make a conference call and hold up to 5 other callers.
With N900 if I have an active conference I cannot even call a 3rd number and leave the conference on hold. Is there a software limitation related to the Phone application? Can it be changed?
Thanks!
