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!"
Why the crack on Alltel? Lame. I switched over from Verizon about 6 months ago and am digging it.
I wish Alltel did get more phones, sooner -- I guess the economics make more sense for Moto to push them to the big boys first...which sucks because that only gives Verizon more leverage to screw its consumers..
