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!"
Seems that DoCoMo didn't want to bother with that rebranded Nokia 6630 they were looking to launch with. And if this means that their handsets can be picked up by importers, it can only be a good thing.
Just a question though - what's this about increased competition in the mobile phone industry in Japan? I haven't heard anything about new entrants...
