The new Moto X will reportedly hit all four major U.S. carriers on Aug. 23, but AT&T will have exclusivity on the customization options until November.

Motorola was not very specific about the actual carrier release date of its brand new Moto X flagship. The company only offered a vague "late August" timeframe for the handset's availability.

A recent report from AdAge claimed that the Moto X will go on sale on Verizon, AT&T, T-Mobile and Sprint on Aug. 23. A newer report from Android Authority, points to an inventory screenshot from an "unnamed major retailer," suggesting that the handset will arrive to Verizon stores on Aug. 15, but will not go on sale until Aug. 23. That's three days after the new Motorola Droids are expected to hit Verizon.

The AdAge report did not only claim the Moto X will be in stores at all four major carriers starting on Aug. 23, but also notes that the customization options, which allow interested buyers to design their own smartphone, will remain exclusive to AT&T until early November. The other three major carriers will get to join the party after that.

On the other hand, although AdAge is undoubtedly a reputable publication, that doesn't guarantee the report is accurate. The exact launch dates are still not official and carriers don't seem to be in a hurry to make announcements.

So far, Verizon only said that Moto Maker, the Moto X customization program, would become available to its customers "later this year," without giving any specific timeframe.

Sprint and T-Mobile, meanwhile, have yet to offer any details on their Moto X plans. The three carriers - Verizon, T-Mobile and Sprint - will offer only the black and white color options when they start offering the Moto X, on Aug. 23.

With the exclusive on Moto Maker until November, AT&T customers will be able to choose from a number of customization options, including the color of the back cover, front plate, as well as accents of their new Moto X smartphone.

The Moto X is one of the most anticipated smartphones of this year and it is the first one to come from Google and Motorola since Google acquired the company. While Motorola has its fair share of good handsets, the new Moto X has Google's fingerprints all over it.
