Nullriver's Netshare app that allowed you to share your iPhone's internet connection with your laptop or desktop computer, was pulled from the App Store, as you know. And while early reports indicated the app would be coming back, it's not looking too good for NetShare now. 

While Apple was working with Netshare, it seems tethering is against AT&T's terms of service. So, this is bad news for U.S. customers, but international customers may gain access to the app again. We'll have to wait and see. 

If you previously purchased and downloaded Netshare, however, it should still work on your iPhone.
