Let the hive mind of Engadget get that for you.
"I just switched to Sprint from Verizon about three months ago for the Pre. Then I went for the Hero about a week ago. Now, I miss my hardware keyboard and am thinking about switching to the Moment. I am still able to switch back to Verizon if I want and get the Droid when it arrives. Should I just trade up to the Moment when it comes out, see if I like it, and if not switch to the Droid? Or something else entirely? Help!"
All I can say is, I feel for you voda people. I am on sh***y Vzw. They block everything and charge more than anyone else. Only reason I stick with them is cause of coverage and evdo. Oh how I long for an unlocked gsm handset...
