Some new additions I noticed.
TouchFlo 3D from Touch Pro 2 with new calendar and My Contact Card functionality. Weather tab is also different. Also, Internet tab included a quick search bar just like how Manila 2D used to be.
OEM has couple of additions like SMSaHo have no clue what that is, figure it has to deal with SMS. Audioboster and streaming got new icons.
EDIT: SSMaHo is a Manila Patcher can be found here
