It works for Alltel,bell, cricket,lusacell,qwest,sprint,telus,tnz,uscc and verizon. It's built with a dcd rom so it uses the carrier files from there. You flash the rom, then install the appropriate carrier file after first boot to enable data.

Free ram, not sure, should have checked but mine has been setup and programs installed for my needs. He has a fully loaded, minimal and kitchen available on his site.
The thread on XDA might give you the ram numbers you seek. but it is responsive and no resets so far. It works.
