iFun turns your iPhone into PC game controller
An accelerometer for Facebook connect
We already took a look at Zooz Control, which intends to integrate your iPhone or iTouch with PC games, but SGN's similar concepts is looking more toward Facebook integration than standalone PC titles.
iFun has kicked off by giving you the opportunity to play Golf on Facebook, using the handset in a similar fashion to the WiiMote. The system boasts full Facebook connect integration, and is looking to include bowling and baseball games very soon.
Social Gaming Network, the developer behind the free iPhone app, has a pretty decent collection of Facebook applications under its belt, so iPhone-owning fans of its community games might want to head on over to the official iFun site and sign up.
