After pwning 2.0 will you be able to use appstore applications as well as older installer applications? For example, iComic is not available in the appstore, but it is available on installer for older firmwares. Will they need to be ported over? One particular app I use often is the SugarTracker and I was afraid to upgrade to 2.0 in case I wouldn't be able to use the app anymore. Anyone know anything about this?
