I've been browsing various web sites along these lines lately, although I've mostly decided that I'm waiting for the Nokia 6200 and I'll probably buy it sight unseen.

That said, here are the cel phone web sites that I prefer. They all pale in comparison to, say, the good camera review sites or any of the computer review sites.

mobile.burn.com -- not bad, but it uses enough JavaScript to confuse my anti-advertising filter

MobileMag - more general than just phones

PhoneScoop - tends to have first photos of new phones but short on details
