Thanks to Apple Inc., CEO Steve Jobs, next gen Apple iPhone 4.0 is finally got surfaced after Gizmodo leak story, Vietnamese leakage etc stories and rumors,
Apple iPhone 4 is still 3G unlike Sprint Nextel HTC EVO 4G which is said to be the only and Very First 4G cellular handset of USA / the world,
|Facetime Video Calling|
Have a look, comparison between iPhone 4 and Sprint HTC EVO 4G,
iPhone 4.0 (with OS = iOS 4) has two cameras, including one front cam for a live streaming international FREE HD video calls (video chat or video conferencing) over WIFI to WIFi, iPhone 4 to iPhone 4 in portrait and landscape modes (this free video calling will not consume the cellular minutes instead its over the web video calling using WIFI data network and in between ONLY iPhone 4 to iPhone 4 later it may come to other networks too, may be, when they will support video calling speed etc),
Apple's iPhone 4 also has gyroscope technology for future gaming, multi touch Retina display with fingerprint resistant oleo phobic coating, iBooks, voice control, LED flash and HD video recording, its said to be a thinnest smart cell phone,
Apple iPhone 4 to iPhone4 free unlimited video calls or FACETIME app could consume large bandwidth that is why this facility is only right now available on WIFI networks and not on any international cellular carrier or AT&T 3G cellular network (iPhone's exclusive US carrier) as 3G etc networks may feel uncomfortable to give large bandwidth on VIDEO CALLING due to pricing and speed etc: )
iPhone 4's dual cams (front and rear) are useful for making unlimited video calls and have a unique and new feature: FACE TIME button…the Face Time app is an open source video call app (SIP, H.264, AAC, STUN, TURN, ICE, RTP, SRTP) thus Apple's Face Time video calling app also will work with other video calling apps) released by Apple Inc. and as Steve says APPLE will bring 10s of millions of Face Time devices in 2010...
If you are not in the range of a WIFI hotspot, do not worry, still you can make video call with iPhone 4 FaceTime using a 3G cellular network, nothing to hack or jail break, its legal, just have a Novatel MIFI (in USA) (its known as EGG or WiBro in South Korea, in UK 3 Mobile sells this) MIFI is a compact wireless router which creates a free personal WIFI hotspot on the go, MIFI converts 3G cellular signals into WIFI, but you have to check as it may cost you as your cellular minutes may be consumed and it may cost you dearly, the video call eats a large bandwidth and I am not sure if using MIFI, thus creating a cellular to WIFI network could cost you what, unless you are on an unlimited 3G cellular plan!
