If you blinked, you probably missed it. The 8GB Google Nexus 4 is again out of stock after being briefly back in stock. Google has updated the product page on the Play Store to simply say "Out of Stock." The 16GB version of the phone, a bit less popular due to its higher price, will ship in 6 to 7 weeks according to the product page.
The device features an incredibly low price when you factor in the fact that it comes without a contract. My iPhone was this much, but I had to resign a two-year contract. The general consensus is that Google is subsidizing the phone to continue to take away market share from iOS and other smartphones.
It's not clear when Google will have more stock of the budget-priced and feature-packed smartphone, but we'll be sure to let you know as soon as we do so that you'll have the best chances at getting one.
