If you’ve ever wanted to identify when your app is being run on a specific device iOS model, in order to limit or enable certain functionality, you’ll have noticed that Apple’s doesn’t provide a way to return the exact version number in its model method to the UIDevice class. Erica Sadun’s UIDevice Extension adds a category to your UIDevice and provide access to a more precise hardware model string. Today’s new release includes a way to identify not only the iPhone 4, but also whether it’s running on AT&T or other carriers.

Other hardware specs like the CPU and bus frequency and total or free disk can also be queried. (via Dr. Touch on Twitter).

Update: As Will Strafach points out, it also identifies an unreleased ‘iPod Touch 4G’ and something called the ‘iTV 1G’.

Aqua Globs Developer Shows iPad Piracy Rates Dwarfing the iPhone

Joost Schuur — Wed, 25 Aug 2010 21:30:33 +0000

The iPad is shown to have a 50% piracy rate, as opposed to the iPhone at only 5%, which developer Vladimir Roth attributes to the relatively high cost of iPad games. See also, Jeff LaMarche and David Wooldridge’s recent thoughts on battling piracy by addressing consumers. The story points to an interesting side effect of systems like OpenFeint: the ability to get concrete numbers for a game’s piracy rate by comparing leaderboard submissions to sales figures. The game is actually really well done and fun to play. It’s like Flight Control meets Osmisis. The full iPhone version is currently available for free for the launch of the iPad version, which itself is now only $1.99.
