Android - is a Mobile Operating System by Google which can be installed on any phone (just like Windows can be installed on any PC).
- HTC Desire C (only disadvantage no flash LED) 14.5k
- Sony Ericsson Xperia Neo V or Mini Pro (both have ICS - slightly old phones - available at 12.5k & 11.3k respectively - battery poor but otherwise decent phones)
- HTC One V (almost perfect phone at 17k)
