After first making Nullriver's NetShare application for iPhone and iPhone 3G available via their App Store, and then pulling it, and then selling it again, Apple has once again pulled the app from public sale. It comes up in iTunes Store search, but generates a "currently not available" message when clicked." Via MacDailyNews .
I purchased NetShare after I read about the app being pulled from the App Store and then being added back. I was surprised that the application even made it into the App Store especially because AT&T does NOT offer a tethering plan for the iPhone 3G. AT&T offers a tethering plan for many of its phones and charges customers a monthly fee for the service. It looks like AT&T might have pressured Apple into removing the App. AT&T would rather charge customers a monthly fee to use the iPhone's 3G network to share its internet connection with a computer instead of Apple selling a $9.99 application that allows customers to do this with no monthly fee.
I tethered my MacBook Air to my iPhone 3G using NetShare and can confirm it works. If NetShare somehow makes it back into the App Store (it's been added and removed twice) buy it, it beats paying AT&T a monthly fee.
