Sony is developing an Android 2.1 smartphone that has a slide-out QWERTY keypad and a 5-inch screen, according to a leak from fan forum.

They are becoming larger and larger. HTC’s Evo 4G had its reign for awhile (even before its official launch), but Dell’s Streak is biggest in July. However, Sony’s alleged prototype piles on a full sliding QWERTY keypad with its 5″ display. The person who leaked this photograph is reputed to have been dependable with his information in the past.
