Nullriver has just released a $10 app to the Apple App Store labeled ‘NetShare’ we’re not sure how long this app will be allowed for. It circumvents Apple’s stance on not allowing tethering on the iPhone 3G. The bad news is that there have been reports of the app not actually working. We’ll keep our eye on this app and let you know how it goes.

Update: Netshare was taken down then put back up and is now reported to be working.
