I've upgraded to a blackberry curve. I set up all my BIS BES etc. I can receive all my work and personal emails. The problem is that when i schedule a meeting and want to invite somebody to the meeting the option for inviting an attendee does not apear in the menu. I've called the mtn corporate held desk hunders of times and still this is not resolved. i have a colleague with the same phone, but she is on vodacom and can do this. please help.
