Breaking a contract and SWITCHING carriers are two different things. But I don't expect you to understand that concept.http://allthingsd.com/20120126/nine-out-of-10-iphone-buyers-are-picking-the-4s/
42% broke their contract -- guess it wasn't that difficult to break a contract after all
If the iPhone 4s wasn't on Sprint and Verizon - it's a no brainer that the 4S would have sold less. The proof is in history.
ETA: Who on this thread said in this thread that Apple failed "big time" (or at all) with the iPhone 4S. We already know you are uber-sarcastic...
