Arne Hess of the::unwired has just published an extremely thorough comparison of four excellent WM phone cameras in the HTC Touch Diamond, the HTC Touch, the Samsung i900 Omnia, and the Sony Ericsson Xperia. The article features many, many side-by-side photos, so if you've been wondering how these 3-plus MP cameras really stack up, this is a great place to start.

Check it out.

It's a shame he didn't include the Toshiba G910 and the Imate 9502 in his comparison.  I've been reviewing both of thos recently and have been very impressed by their cameras.
