It can be found in this X8 thread:
Update 1: Ok, it's confirmed to be working! Just download the SuperOneClickv1.5.5 (for 2.0.2.A.0.24).zip file below!
Update 2: SuperOneClick has been updated to use psneuter for exploit by default. This means easier rooting of SE devices. Original thread here. I have attached the latest version (1.6.1) below
Update 3: Have attached version 1.6.3 of SuperOneClick. Original thread here.
Update 4: This works for those who have updated to 2.1.A.0.435 firmware as well. If you have problems with version 1.6.3, please try version 1.5.5 instead.
Update 5: Attached version 1.7, which works just as well.
Update 6: This does not work on Gingerbread Android 2.3.3! You can either download and flash one of the pre-rooted custom ROMs found in the Development section or follow DooMLoRd's guide.
