I've had Fring loaded for over a week and did not get a notification for an update with the iphone announcement. So, it appears to be the same version as I've been running. I have used mine with no problems (EVO, unRooted). My brother also has an EVO and we have used the live video chat option. Works fairly well over 3G, but need a head set to kill the audio feedback loop when using the speakerpone. Haven't tried WiFi or 4G yet, but I'm sure that will only improve the performance issues we saw with 3G. Anyway, it's working for me.
What handset are you using and what version of Android is it running?
