Sony ericsson cedar also known as j108i is a good phone for optimal usage. I have got one for myself for Rs.5500.i would recommend this phone if you want to buy 3G capable phone under 6000 only bit disappointment is that CEDAR doesnt have front video calling camera though its 3G phone. if you want to have video conversation the only option left is through back camera.
App integrations such as FACEBOOK, TWITTER, LINKEDIN are included. 3D gaming works well as well as the sound quality not from the speakers but from the headphones.Speakers lag behind when playing music or videos. Camera quality is not too good under dim conditions but also not too good when taken in bright conditions. images tend to blurred or noise in bright conditions. so the camera quality is not too good. This phone is purely good for internet usage, games and apps and listening to music (through headphones).
