"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!"
No, they're trumpeting adding 1 million gross subscribers, but when you subtract what they lost you get the net adds of under 400k.
Now that's nothing to write home about, but anything is better than the net losses Sprint keeps taking quarter after quarter.
