If you're looking for some games to play on your iPhone, Jason Merchant has a couple of interesting ones up for download. If you like fish and you've got issues with Microsoft's Zune, you'll love these.

Aquarium v1 is a simple application where you can watch fish swim around, then feed them if you wish to do so. It's actually very relaxing to do this, and will probably kill a minute or two when you're stuck in traffic.

A more heart-pumping application is the Shoot the Zune wherein you play the role of the iPhone and launch missiles at hapless Zune MP3 players across the screen.

Please be reminded that you'll have to Jailbreak your iPhone first before these can be installed. They're written in objective C. Tweaks have been made from previous versions of the apps.
