Many people has asked whether mobile substrate doesn't work for game cheats, and rightly so. This post should clear thins up a bit.
To begin with, there are 3 main types of MS(mobile substrate) cheat. Logos (usually seen here as a normal MS hack, and with the prefix MS on topic titles). These type of tweaks WILL NOT work for any device jail broken on iOS 7 as of writing. This is due to the APIs that the current substrate uses being not compatible with iOS 7 as of now.
The second type of MS tweak is MSHook. (Prefixed with the same name on topic titles here) Again these will not work on iOS 7 for the same reason stated above.
The last type is code inject hacks (prefixed with MSCI or MSInject here). These WILL work for any 32 bit device but for 64 bit devices, it depends on the game. If the game has no 64 bit section then it will also work, however if the game does have 64 bit code then the tweak will not work
Hopefully that has cleared things up for people looking for hacks :)
