NetShare - share iPhone's network connection

There was a method to use IPhone's internet connection on a desktop (Get internet on a desktop or notebook through IPhone 3G), now there is an officail one:

NetShare is one app we never thought would make it onto the official iPhone App Store. The $9.99 application promises to allow you to share your iPhone's network connection with your computer. All it does is set up a SOCKS5 proxy for you to get your laptop/computer online through use of the 3G/EDGE connection. Does it work? Yes. Yes it does, much to our surprise. EDGE works just fine, although Mahoney says it's slow as balls. 3G impressions in a sec. Be careful of how much bandwidth you're using, since your provider probably makes a frowny face at you using their network to power your laptop, however "unlimited" your plan may be. How this got passed Apple and AT&T who knows.

Link to AppStore: NetShare. Tutorial is here: NetShare HOW TO.

Update 1: There are some bugs with iPhone 3G.

Update 2: The application is gone. Now we're getting the message that it's not available in the US store

Update 3: Just an official reply from Nullriver:

"We're not quite sure why Apple took down the application yet, we've received no communication from Apple thus far. NetShare did not violate any of the Developer or AppStore agreements. We're hoping we'll get some feedback from Apple tomorrow. Sorry to all the folks that couldn't get it in time. We'll do our best to try to get the application back onto the AppStore if at all possible. At the very least, I would hope Apple will allow it in countries where the provider does permit tethering."

Update 4: The application re-appeared in iTunes. It is avaliable through direct link: NetShare.

Update 5: It's gone.. again.
