After being stupid frustrated on how to do this as the features to do so have been missing from most/all stock ROMs, I've decided to gather up all the files needed to easily get your MSL#.

Tested on MidnightRomJB 1.0.8, but should also work on all other TouchWiz based ROMs.
(This feature will also be integrated into all future versions of MidnightRom)



-Start by downloading the MSL Toolbox Fix that I packaged together, and install it on your phone using recovery (File attached)



-Download/open Terminal Emulator from the Market

-Type in (Exactly)

Annd...BAM! The number that is shown is your MSL! Easy as that.

Enjoy all the MSL related goodness ^_^

 

Fixed the zip file as I was overly tired and messed it up when I uploaded it lol.


Also, sticky?
