Apple Continued To Lose U.S. Marketshare Despite Spike From iPhone 4 Sales

Apple’s iPhone 4 did not give the company the bump in sales it needed to put Android’s momentum in check.

Barron’s reports that the analysts strongly believe that if Apple expects to ward off Android, they need to add versions of the phone for the large carriers that don
