One of the greatest features missing from the iPhone has been the ability to tether it to a laptop. NullRiver is making this feature possible by releasing their NetShare software. Here is the description from the AppStore:

"Share your iPhone's EDGE or 3G Internet connection with your computer using NetShare. NetShare provides a SOCKS5 proxy for your computer to connect to."

So basically what this does is turn your iPhone into a wireless modem for your laptop to connect to the internet when there is not a connection around. There are still some bugs to work out in the software but it is looking very promising. It is currently being sold for $9.99 on the AppStore. If anyone tries it out, please post your feedback and let us know what you think.
