HTC is not possible. Motorola Defy+ is there & its overpriced. Neo V but then you don't like Sony mobile. so only option left is Galaxy R but will cost 20k. on the lower side you can go for the original Defy or Defy+ if you don't feel its overpriced.
yes. all mobiles above 15k can be updated to Android 2.3 & some to Android 4.0. you may look at the mobile reference guide. then you can jump to the exact mobile you want in minimal time.
Htc Desire is 22-23k but I have to think again,no problems with it?
Htc Incredible comes with 2.2 right so can we get ICS update for that or 2.3?
