K800i or K810i?

Do you want to change your handphone or cellphone? I want!! I want to change handphone but not the same brand again.. because it's fitur always not complete :(
I can buy new handphone with complete fitur and also cheaper. I try to find the new one and it's includes 3G, by the way, now i don't need to use 3G.
I already saw and find so many website and price of K800i but K810i still not launch in the shop. So i has to wait for it. I think about price, i have to wait again, because, SE(sony ericson) prices always fall down if there is new product from factory.
Do you know about the other handphone again, that same rate and fitur?

specification of K800i, i got from www.studiohandphone.com
