Today Google decreased the price of the Nexus 4 by $100. If you are in the market for an excellent unlocked GSM phone, this price is hard to beat. Sorry no longer available.
However, I suspect the reason for the price drop is to clear out stock for the rumored Nexus 5 that should be unveiled soon, likely in the next couple of months along with Key Lime Pie KitKat (Android 4.4). If you want the latest device, you probably want to wait until the Nexus 5 comes out.
I wish they would make real Nexus CMDA devices so I could buy them to use on Ting, my favorite carrier by far… unfortunately that hasn’t really happened yet. The closest thing available for CMDA users is the aging Galaxy Nexus and it doesn’t get updates nearly as fast as the GSM versions.
Thank you Google for making a real CDMA/GSM unlocked device. It is unlocked to work on any carrier, only Verizon LTE bands are left out (probably because Verizon doesn’t want unlocked devices on its network… that’s pure conjecture on my part though).
