iPhone 4 Tops Phone Sales, Is Most Popular Phone

Chalk up yet another accolade for the iPhone 4. Though Apple's latest phone may have gotten off to a rocky start with the antennagate debacle, market research firm NPD is now reporting that the iPhone 4 is the best-selling device -- this includes both smartphones and feature phones -- in the U.S., according to Q1 numbers.

iPhone 4 sales, boosted by the February launch on Verizon, drove Apple to become the third most-popular phone manufacturer, coming in behind Samsung and LG. The top 5 are:

1. iPhone 42. iPhone 3GS3. Motorola Droid X4. HTC EVO 4G5. HTC Droid Incredible

Android still dominates on the OS side, though Google's mobile operating system lost marketshare for the first time since 2009 and Apple moved up 9 points to 28 percent. RIM had a rough quarter, losing 5 percent, which puts the BlackBerry OS on only 14 percent of smartphones.

Also, for the first time ever, smartphone sales have outstripped feature phones, with smartphones making up 54 percent of all new phones purchased in the U.S.
