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!"
RU KIDDING???????????
It's something that can be done for FREE by your neighbor, your average 5th grader or even your cell phone reps at your local Sprint, Verizon or wherever you carry service!!!
It's BT pairing, not DNA splicing??!!!!!!!!!!!!!!!!!!!!!
If it's DNA splicing you're after, you're better off trying match.com. Not some pimply-faced kid at BestBuy.
