they (i.e. c4eva (the guy who basically codes the firmware)) are already currently working on firmware that gets around the recent bans.
basically the new Abgx360 v1.0.2 application and the new 'iXtreme LT' will get around the current ways of detection recently. but only Abgx360 v1.0.2 is out right now. the new iXtreme LT ain't out yet.

p.s. i most likely won't be signing into XBox Live anymore on my console simply because if you do get banned you will lose ability to copy games to hard drive which basically will semi-disable games that are on 2 discs like Forza 3 (which is my favorite game on the console) since the only way to use the 2nd disc is to copy it's game data into the XBox360's hard drive. plus not to mention any games i use alot i always copy the game data into the xbox360's hard drive simply because it puts less wear and tear on the dvd-rom's laser since it only verifies the game disc and after that all data is loaded from hard drive.
