Do you want the new LG G4? Well, go call dibs. That's not what this post is about. We're gathered here to talk about the G3. It's still a good phone. Only now, due to planned obsolescence, it's becoming a cheaper one. On eBay, you can get an unlocked GSM model for a pretty reasonable $340. This is the 32GB model, which AT&T still sells for $450.
These are new units, not refurbished ones. They're intended for use on AT&T's network, but you can take them to other GSM carriers, though T-Mobile customers may find that some bands don't quite match up. The phone is available in your choice of metallic black. The seller is willing to sell to various parts of North America, Europe, and Asia. Australia's also included. Shipping is free.
