Has anyone got problems with Visual Voicemail? I've now been asked to set a password and set a greeting twice. This must have worked because when I ring my number from another line I get my personalised message. I discovered last night that I wasn't being advised of new messages, and have left myself 2 messages this morning (23/11/07) with no alerts on the iPhone to advise me. Is there a way to 'call' voicemail to check like on other networks/phones? My phone is a bog standard UK model on O2, not unlocked/hacked etc.
