I have the Curve on the T-MO network. Maybe it's just me or something.

I have noticed that none of mine blackberry Messenger requests have been approved nor can I any request to anyone else. I don't know what the deal is and I wish I could figure this out.

Pull the battery, reboot.

Make sure you make the BBM invite via PIN not email. When using the invite process, press menu to ADD BY PIN. I've had a few not get added that were send by the BBM option to send as email.

Try that.

See I have done that and still I can't seem to get it to work. 3 BB in this household two of the three work and the one that doesn't work is mine. UGH!

Honestly, I had the same problem recently when I switched over to my 8310. I could not add a couple of friends, as it kept being "pending". I think (and you have probably done this) I deleted ALL entries referencing those people, and asked them delete me as well.

Yes and I JUST tried to add me again and now I can't invite via "pin" it's only email. Of course it has go the other direction for me. One step forward with new phone and 340 steps backwards with problems.
