Video calling: Android does not support native video calling, but some handsets have a customized version of the operating system that supports it, either via the UMTS network (like the Samsung Galaxy S) or over IP. Video calling through Google Talk is available in Android 2.3.4 and later. Gingerbread allows Nexus S to place Internet calls with a SIP account. This allows for enhanced VoIP dialing to other SIP accounts and even phone numbers. Skype 2.1 offers video calling in Android 2.3, including front camera support.
The TOPIC of our conversation was not about patched or modded phones. Nor single function features. The truth is that Apple fully supported the front facing camera when the iphone 4 came out back in 2010. Android had nothing of the kind. Now if you wanna argue about who made the first camera phone with wifi connectivity then it's a Symbian based Nokia from 7-8 years ago.
So As i said earlier: GET YOUR FACTS RIGHT!!!!!
Who cares? No iPhone on 3G is going to run Skype like a DROID RAZR MAXX on Verizon 4G LTE. It's insane, it literally has lower latency than circuit-switched voice.
