Alright, That's good enough for me.
Well, as you know, the ROM itself is not over 160MB - what KonstaT means is that the ROM + GApps are over 160MB.
So, if you want, you can trim the GApps too (I did as there are Google 'things' I don't use) like "Talk" that was replaced by Google.
In the ROM you can trim the "LatinIME" as you said yourself (14,313KB to around 3MB), you can remove the BootAnimation, you can remove unused sounds (not much to gain though) and you can remove some Apps (you must be sure of what you're doing) like:
"calculator" - you can install it later (the same or another one); "email"; etc.....
I think trimming the LatinIME is enough.
thanks a lot dreis.
