HTC EVO 4G
OK, this phone probably doesn't make sense for people in India, who are still a few good months away from getting 3G. The EVO 4G is a CDMA phone with support for WiMAX. WiMAX is that next generation tech that's also referred to as 4G for the sake of simplicity. It's one of the 4G technology, the other one being LTE. Enough with technicality, let's talk about what it can do for you.
In the US, where its sold by CDMA-based carrier Sprint, they say it can hit up to 10 Mbps. That's enough to let you stream HD videos on the phone, without aimlessly staring at the wall/window/whatever for a few minutes, waiting for it to buffer. The screen is a visual treat at a humongous 4.3 inches. A Qualcomm 1 GHz processor takes care of the number crunching. An 8 megapixel camera lies at the back, and a 1.3 megapixel camera at the front - which is better than most phones that have a 0.3 megapixel front cam.
So, if you live in the US and feel that 3G speeds aren't fast enough for you, take a look at the EVO 4G. The rest of the world, go back to staring at your HSDPA-ready phone.
