The low-cost but still fully-featured Moto G had an expected release date of January in the US, but Motorola unexpectedly began taking orders for the devices on its own website on Tuesday and says it will begin shipping them in December.
"We're giving people plenty of mobile goodness to gobble up this holiday season," the company said on its blog, ahead of Thanksgiving.
The device is being sold at "one third of the price of current high-end phones, for a smartphone stuffed with plenty of great features," it said.
The Moto G is far from the fastest handset out there with its 1.2GHz quad-core Snapdragon 400 chip, 1GB of RAM, and lack of LTE, but the phone does boast a hefty 'all-day' 2070 mAh battery and Android 4.3 Jelly Bean.
The unlocked handsets are selling for $179 for a model with 8GB of onboard storage or $199 for a 16GB model. Neither version has a microSD card for expansion, but both also come bundled with 50GB of free storage on Google Drive for two years.
The phone is about one-third the cost of an iPhone.
For either version of the phone, users can also choose between a chipset that's been optimized for US 3G (UMTS/HSPA+) networks or one that works best on global networks when roaming outside the US.
Google bought Motorola Mobility back in 2011 for US$12.5 billion.
Details on an Australian release for the Moto G are still not available.
