Messed around with CoDMaster's unbanner for Tekno and added some features for IW5M.
Short of an IP-Ban, you'll get unbanned from MOST, if not all servers.
Fixed Null Name (Name Changing to "...." or "thisguyhax")
Fixed Random Crashes (As experienced with Barata's Teknohook and the original Unban Bypasser)
How To Use
INJECT ONLY IN MAIN MENU. (WAIT 5 SECONDS PRIOR TO INJECTION)
For TeknoMW3, just join a server for it to auto-activate as with all versions.
For IW5M, on the "Connecting..." screen, press Shift+Enter within 5 seconds. Your name and GUID automatically resets to the original within 20 seconds. This does not occur with TeknoMW3. I have verified this is patched on IW5M. Do not complain if, in your ignorance, you use this and get banned.
