The RAZR2 will be available in at least three versions: The V8 will support EDGE, the V9 will support HSDPA, and the V9m will support EV-DO. The V8 will be available in July, while the V9 should be out by Q3.
Motorola has been vague on the differences between versions of the phones, but at least one version (probably the V8) will run on Motorola's Linux-based OS, while others will get the old Synergy OS with an updated user interface.
Motorola also confirmed that the "Media Monster" phone CEO Ed Zander hinted at earlier this month is indeed the Moto Z8, which first appeared months ago at 3GSM.
