As we (users of Howardforums) update this thread, I will update this first post with the facts we have come up with.

My blackberry is dieing. So now it is time for a new phone. I know without a doubt that I want an Android based phone. Switching carriers is not an option so my new Android phone needs to work on the CinBell 3G network.
I am trying to compile a list of working Android phones for the CBW 3G network.

Here is what I know so far. For a 3G phone to work on Cincinnati Bells 3G network it needs to have the frequency band AWS. I believe this is also called UMTS bands IV (4) frequency 1700 and 2100. So does that mean that any Tmobile 3g phone unlocked will work on Cincinnati Bells 3G?

Lets start with the obvious. (these work because I have seen post with people on CBW with these phones.)

Nexus One (HTC Dragon)
T-Mobile G1 (HTC Dream)
T-Mobile My Touch 3G (HTC Magic)

The following may work. (based on googling and reading the specifications of each phone.)
Motorola Cliq
Motorola Cliq XT
Samsung Behold II

I hope to get some feedback and make this the goto list for CBW customers looking for an Android phone.

Thanks for everyones help.
