Apple's iPhone 6 is totally crushing it right now

The latest monthly wireless store survey from Canaccord Genuity analyst Michael Walkley shows that Apple's flagship 4.7-inch iPhone 6 was the best selling smartphone at AT&T, Verizon, Sprint and T-Mobile in September and through the first portion of October. The larger 5.5-inch iPhone 6 Plus also came in second at all four major U.S. carriers.

Walkley said his data showed that the new iPhone 6 series was "by far" the top selling smartphones at all carriers and channels. However, the surveys also found that Apple is experiencing "very limited supply" for its latest generation devices.

The poll found that the iPhone 6 Plus was completely out of stock at all four U.S. carriers, with a typical wait time of two to three weeks or even more. Availability of the iPhone 6 was better, but still "very limited" with a typical wait time of seven-plus days, Walkley said.
