Upgrade SonyEricsson K800i to 810i?

is it possible 2 upgrade SonyEricsson K800i to 810i? n let me knw how...
Thankz in advance

k810i is very much a like than k800i, the only difference is the exterior, but the camera is still the same, so upgrading the k800 is not a good idea, if you want to change your k800i, go for k850i instead. http://gsmarena.com
