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!"
Great idea! Until you lose the headset, then your phone looks broken and it would probably cost alot to replace it =(
So scrap the whole idea because you lose stuff. Hell, scrap cell phones while you're at it. I've lost one of those before...
haha calm down, I was just pointing out how it would look strange if you misplaced the headset. I think its an ingenious idea, and it makes carring a phone and a headset easier.
