Is the 'Lumina' meant to be snide or a general misspelling?
His Amazons link seems a bit suspect, the iPhone 3G 8GB is the best selling unlocked phone, unless that's just how things roll in the states.
Now, about this Lumina phone, only drawback seems to be the screen. On the advertising side, yeah it's confrontational and this is an Apple site, but the Droid/iDon't etc. ads seemed to work don't they. AT&T want a new hero phone and the 900 may just fit the bill.
