New app lets your Mac share your iPhone's internet connection

The $9.99 NetShare application from Nullriver, Inc. was released to much excitement on Thursday evening but inexplicably pulled from the App Store by Apple moments later.

"We're not quite sure why Apple took down the NetShare application yet, we've received no communication from Apple thus far," the company said in posting to its website. "NetShare did not violate any of the Developer or AppStore agreements. We're hoping we'll get some feedback from Apple today."

In an email to AppleInsider Friday morning, a representative for Nullriver said the company was still "trying to get a hold of Apple" and was unsure whether AT&T was involved in the matter due to data use concerns.

Nevertheless, Friday afternoon saw the application suddenly resurfaced on the App Store via this link. NetShare is a tethering application, or one that connects a non-mobile device such as a desktop or notebook computer to a mobile phone for the purpose of wireless Internet access.

For example, the application can provide a Mac or Windows-based notebook with a connection to the Internet anywhere an iPhone has an EDGE or 3G signal. This is particularly handy for users who don't have dedicated 3G data cards and service for their notebooks when traveling.

Update: AppleInsider has published an illustrated 10-step configuration guide.
