It is great to see Fring support the iPhone 4 since it should expand the number of people I can hold video calls with, but I would rather have a working client with Skype support than more iPhone users on the network. Support for Skype was a major reason I use Fring over clients like Qik because it allows me to call family and friends who are on Skype with their laptop or desktop. Fring states this is a temporary reduction, but I haven't seen anything on when they might have servers back up to support Skype.
You can still make Fring-to-Fring calls between Symbian, iPhone, and Android owners so maybe this is a way to get more people to adopt Fring as a video call client. Have you tried using Fring on your supported smartphone?
