I figure it’s worth mentioning this because I just noticed this while browsing AppShopper.
In August, Konami released a new version of DDR for the iPhone called DDR S+. Using iPhone OS 3.0’s StoreKit framework, they let you buy song packs and essentially build the DDR song library up yourself. It’s being sold for 99 cents.
That’s not the new part.
The new part is that they reused DDR S Lite’s product ID to sell DDR S+. Meaning that everyone who downloaded the Lite version of DDR S prior to its release gets a free upgrade to S+ if they redownload it.
