Hacking Paid Upgrades in the App Store
David Smith (via John Gruber):
So long as you don’t actually delete the old version of the app within iTunes Connect you can continue submitting updates to apps even while they are in the Developer Removed from Sale state. Whether this is intentional functionality is unclear but I have verified that it does in fact work and the resulting approved updates are available for customers.
This is good news, although I still think the App Store needs paid upgrades. One of the strange things about the “hack” is that the store will notify users about minor updates to apps they’ve purchased but not major ones.
