This Apple Insider article has the details.
For the U.S. Smartphone Market (from comScore's MobiLens):
Apple did increase its share relative to Android, but given the timing of the release of the iPhone 5 and the aggressive pricing of the iPhone 4S and 4, that is not shocking.
What is shocking is that Window Phone Lost market share during the period. Windows Phone 8 got lots of buzz and the Lumia got rave reviews. This is really not good news for Windows Phone.
