Hi friend,
It is all depends on your choice, means which facilities toi want and how much rupees toi are ready to to spend for this. Actually Motorola Back Flip and a Lg Zenon all these are really best mobile. And these features are also nice. But i like LG Zenon very much. The LG Zenon is a quad-band GSM handset that features a side-slider design with a 2.8 inch touch-sensitive display and a full QWERTY keyboard. This touchscreen phone also carries a 3 megapixel camera with digital zoom and video recording. The LG Zenon offers a nice set of features which include 3G support, Wi-Fi, A-GPS, Stereo Bluetooth, media player and a microSD/microSDHC memory card slot.
And i like to say Motorola Back Flip phone had a good idea, but I feel like they came out with it too early before they had alot of the kinks worked out. Perosnally I would stay away from this phone. Still toi confusion......? Then I have another useful information about mobile phones. toi can find here
link It will be very helpful for toi to chose right mobile.
