I don't own a 360, but I'd like to get the scoop on playing live before buying a 360. with a rgh jtag Latest Dashboard and Dashlaunch Coolrunner Rev C Installed (the 360 I'm interested in) can I go online with the system? how would I be banned if I did go on live? arcade live ban possibilities? does the microphone work with all live games? can I need friends codes to chat like the wii? does every game that'll play online demand xbox live gold - including arcade live?
