So I've installed External to Internal SD Mod [Latest 1.12.30, Updated 02/01/12] and it worked fine. Prior to installing it I had the latest MIUI rom installed, but now under my phone info it says 1.12.30 is installed and it keeps bugging me about installing a MIUI update to latest version.. I didn't think it would "replace" the whole rom, just add the tweak. So is that the case (did it replace my newer version) or does it just SAY that it's 1.12.30 but it's actually the same rom I had earlier but with the SD mod.
If the former, what happens if I update, will the tweak disappear?
