JK4, JL2, JK3, and KP1 are probably the main ones you see being used.

Captivate Android Development - Page 2 - xda-developers

There is more than one MODEM thread, and not a complete list anywhere... so search from the above location :).

They are almost always clockwork ZIP files that you flash in recovery, but a TAR file would be done through Odin (PHONE). You may be in an area that does not have 3.14159G enabled very widely. If you got/get better signal when your phone was stock or with the older Cognitions, you may be in a HSUPA deprived area.
