Earlier this week, Microsoft started sending out developer-only test units built by Samsung and LG to developers to help them test the performance of their upcoming apps on actual handsets rather than emulators. Folks at NewsGeek site has put this test phone which is running Technical Preview version of Windows Phone 7 against iPhone 3GS running iOS 4 for a head-to-head web browser speed comparison. Unfortunately, since the test was conducted on a (different?) 3G network instead of WiFi (see the Disclaimer below), In all fairness, it will be unfair to pick one winner between Mobile Safari and Mobile IE.
