The LG G Flex 2 isn't as big as its predecessor, which makes it a more practical device to own. Unfortunately, a slightly curved screen isn't really exciting enough for the cost (AT&T wants $709 off contract). But while the G Flex 2 may not be a must-have phone, it's still a nice one. One you can get on eBay for a significantly more reasonable $290. And it will come brand new—not used, nor refurbished.
These are AT&T unlocked units, so you're free to take them over to T-Mobile, but it won't support all the same bands. This model comes in silver. Outside you have a 5.5-inch 1080x1920 display and a 13MP camera, while on the inside you have 32GB of internal storage and a toasty Snapdragon 810 processor (you might even say this deal is on fire).
In the United States, shipping is free. The seller is willing to mail devices out to North America (including Mexico this time) and much of Europe. Australia and New Zealand make the list, but most of Asia and the rest of the world are out of luck.
