I was wondering why my iMessage service does not work on my 3GS phone. The iMessage tab is switched to on. The recipient and I are both within wifi connectivity. The send button even turns blue. When I try and send MSG it says not delivered. When I gO to settings and turn imsg tab off then bk on, it says waiting for activation… How do I activate for starters?!! I have put my password and used ID in too but still to no avail! What do I do? Thanks
