Truthfully, both phones are very bad. Don't get the Wildfire at any rate. QVGA resolution on a 3.2 inch screen is just wrong. Android has few apps that support QVGA resolution screens. Get high end HTC phones, but HTC's cheap phones are terrible. The best thing about the SE Vivaz is the camera. The rest is a flop nowadays. It runs on the very outdated S60 5th edition, and it's OS is about to be completely obliterated, as it's final supporter of a company has planned to give it up. No more software/firmware updates, new apps, and basically everything by 2012. Except the warranty of course. If you are really stuck in choosing between these two phones, Id' suggest.... the SE Vivaz. At least you could salvage some pride with the camera, but the two tap UI is just wrong on it.
