If my HD2 "upgradeable" to HD7 via XDA, I "considering" my HD2 as HD7....

the call quality of iP4 is worse than HD2... the other end sounds too "deep/bass".

Very detail info regarding iPhone(s)
http://knol.google.com/k/iphone-secrets#

So what is the SAR for iP4?

My personal choice in ranking:

1. Fring (WiFi & 3G compatible. Cross-platforms supported)
2. iMovicha (WiFi & 3G compatible. Cross-platforms supported)
3. YM (WiFi & 3G compatible. Cross-platforms limited)
4. Tango
5. Qik
6. Knocking

But all the above are as lag/echo as FaceTime.

Check their website to see which ones supported Nokia model. Remember, Symbian has many variants. Check carefully.

In this case, if both parties have excellent 3G connections, smooth video call is anticipated. But if either one party does not have good 3G speed, it will be choppy/lag.

I've been studying and following the development of Video Calling since like 5 years ago...(though it was introduced way before that... http://en.wikipedia.org/wiki/Videophone ). Until today, none of the apps are able to conquer the choppy quality of the videos.

I do not prefer Tango as it does not have IM function like Fring. Still, I keep it as my iPhone apps.

iMovicha is more flexible as it supports video calling from Windows XP/VISTA/7 desktop to any iPhone/Symbian/WM/Android phones. As Skype does not support video calling thru iPhones and other phones, it will die soon...

Back to TS, Tango is not compatible with Nokia (unless Nokia model that supports Android...any?).

That could be the main reason why none of the video call apps are at the TOP 10 in iTunes /MarketPlace/OviStore
