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!"
That may be the case in Germany, thats true. But not in whole Europe. When you buy "Unlimited Internet" at T-Mobile UK or Virgin Mobile UK, you get also 1 GB "fair use".
But it's still a great value though. 600 Minutes, "Unlimited" SMS (3000 Fair Use) and "Unlimited Internet" for just £20 a month. Try finding an offer like that in Germany, it's impossible i think :/
