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!"
this does sound too good to be true. the thing that scares me is the asterisks at the bottom which says something along the lines of their ability to change the service at any time. thats what would worry me, ill stick to my smartchoice alltel plan
