3.0 and the app store
Apple is requiring all applications from this point forward to be compatible with 3.0 in order to be reviewed. They’re also going to be going back and testing each application already in the store against 3.0.
I only wish at this point that they’d introduced additional backwards incompatibility, or perhaps even just a simple flag forcing each developer to rebuild and resubmit. We’d probably lose about 10,000 apps.
