FaceTime via MyWi :)

So we have 4 iPhones, 2 3GS's and 2 iPhone 4's.

We have no wifi around us so we connected each iPhone 4 via MyWi and it works perfectly!

We tried connecting both iPhone 4's to 1 3GS but it froze up. It was cool though lol

Once the iPhone 4.0 is jailbroken, the app 3G Unrestrictor should work to fool the iPhone into thinking its on WiFi.

We'll see. It's open API anyway. I'm sure Skype and MANY 3rd parties will provide apps via 3G.
