hi,
may this is useful to u....
Sony Ericsson recently announced the new king phone, K810i. It's updraded version of the first Cyber-Shot phone, K800i, or is it? What new does it exactly offer? A better camera? No! Like Sony Ericsson K800i it has 3,2 megapixel Cyber-Shot camera with autofocus. Basically Sony Ericsson K810i is just the K800i with a new design. We could also ask why Sony Ericsson re-releasing K800i? I think because Sony Ericsson K800i was so popular model and they want to keep it that way by releasing the same phone with new design....
