While talking with customer service today, the person I talked to mentioned a new device coming out at the same time as the 8100. I thought she said 8750???

it might be the 8705 .. which is the same as the 8700g, but has Hearing Aid Compatibility, and some gsm radio changes.. nothing major from what i read on Engadget.com...

There are postings all around about this, same as the 8700 but is Hearing Aid Compatible and some real minor changes from what I have read.

Actually I heard the same thing....that T-Mobile is coming out with a Blackberry 8750, and perhaps as early as the end of the month. (September) One of the features I was told it will have is expandable memory.

That would be an incorrect usage of the numbering scheme (not unheard of, but unusual). xx50s are CDMA devices.

I believe the correct number is the 8705. From my usually reliable source.
