I believe the 20270 build is for a different phone but was ripped to work with the touch. The 20270 is for the touch pro or diamond I believe. That os was not designed for the touch but the ppcgeeks made it work. Sort of like a honda civic with a 1.8 liter engine. Sure, you can make an accord 3.0 engine fit if you put in the work and the money but it was not designed to use that engine
. Just my thought
