IPhone 4 - 3G - SIP

I'm using iphone right from the first generation. Somehow apple made a nice user interface which is much appreciated. Eventhough it still needs reboot like windows after using sometimes.

One thing much appreciable about the 4th Version is the open standard. HTML5 and the SIP. With SIP it must be easily interoperable with many services and easier to extend the services to enterprise market. Extending SIMPLE to Iphone 4, also let know about the presence of the user before we call them. So we can avoid voicemails and hit calling them. We can also make automated relaxed call as soon as the other person is available.

I foresee Mobileme will bring video from iphone and you should be able to watch Iphone video from Browser through your http connection. No extras fittings.

Thanks to Endgadget for the photo.

Nice list with the nice interface.

H.264 & AAC is the codec
SIP - Session Intiation Protocol
STUN - Session Traversal Utilities for NAT
TURN - Traversal Using Relay NAT
ICE - Interactive Connectivity Establishment
RTP - Realtime Protocol
SRTP - Secure RealTime Protocol

Also on my dreams I should be able to have more than one phone number for my mobile. With these technologies you have any country phone number to your mobile. Providers such as localphone are readily available on Open Standards to connect with them.

Thanks to Jeff Pulver for creating me interests on these technologies. He made me to make the first VoIP Call to Newyork, USA from London, United Kingdom in 2002. Kudos to Steve Jobs for making the nice graphics workable box again.
