After research of few days, I finally settled with Sony Ericcson K790. I checked Nokia N series and some other Sony Ericsson phones. Sole reason to select K790 , is its Cyber Shot camera. With 3.2 mega pixel it gives sharp and satisfactory results. On first day I was doubtful about results, as it did not fulfill my hopes. But after tweaking all the functions of camera , finally I got some decent shots , of different things in different lighting condition, which I could share with you. I have uploaded them at flickr.com , you can find EXIF data there (image properties/specifications)
