KJ4 - General modem version in 3 letters/numbers. Named generally from AA1 to ZZZ, though alot of numbers and letters got skipped.
Download links are there:
Zip files are CWM flashable.
Bin files are Mobile Odin/PC Odin flashable. Never rename bin files, or Mobile Odin will not recognize them!
Warning: Even if you want to flash bin file with Mobile Odin i advise to download CWM zip file and extract bin file from there, as it will give you extra CRC protection in case your download was corrupt.
ICS modems can be used with GingerBread ROM's and vice versa.
At least i never have problems with it before.
If you have new modem - post it in this thread and i will add it to the OP.
