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!"
re: the old AT&T/NTT DoCoMo. Back then when NTT DoCoMo was a bidder(along w/Cingular) for buying AT&T . . . NTT DoCoMo being a part owner in Verizon would have had to sell their shares in Verizon if they ended up outbidding Cingular.
I'm itching for this to start; maybe it was worth it to move back here . . . hahahaha, maybe. I'm guessing there's no way this will be done halfway. There'd be no agreement if AT&T wasn't totally onboard w/what DoCoMo wants to offer their customers; and we AIN'T talkin' Edge, I'm sure of that!
