Does suck that the 888 number died, wasn't available for other countries for their launch time.
I did the fring test, horrible sound, choppy video but I did pick up on the test girl doing the shocker at the end and she said fring me later but I haven't heard from her since.
I hope the fring quality doesn't represent the facetime quality as people in this thread indicate.
I know lots of people with iPhones, just not a iPhone 4 so I didn't get to test it either, but I'm not too worried about it or giving out my #.
For now, its a fairly useless technology until you can talk via it or skype to desktop clients or other mobile platforms. Hopefully it moves forward sooner than later.
