Open your browser, go to Engadget.com, if you get directed to the mobile version, scroll to the bottom and tap the full Engadget experience link. Did it work, or did it come up with a server redirect error? When playing with Android phones in shops, I noticed that the Xperia X10 couldn't do it, the Hero couldn't do it, the Desire did it once I messed with it a bit, and the Nexus One did it perfectly first time. Were the demo phones in the shops just broken, or is there a bug with the browser? Or a competibility problem with some phones?
