FYI NGR. MaxManila 2.9 DOES work with 2011. However, you need to build it in as a package. I took the maxmanila 2.9 cab file and converted it to an EXT using a cab to EXT converter found over at XDA

Then I dropped into Calkulin's 1.5 b3 kitchen and built a 2011 ROM using a 28223 SYS and it seems to work great. Everything seems to work.
Anyway, check it out NRG.
