If you didn't know already, the Nexus 4 has been a very popular device since it went on sale, constantly going out of stock without minutes/hours of coming back into stock.
If you've been waiting for a Nexus 4, today is your lucky day. Google have announced that the device will be back in stock on the Google Play Store at 5PM today.
If you've been after one without much luck I suggest sitting at your computer, waiting till it's 5 o'clock and then ordering one right away.
The 8GB version is going for £239 and the 16GB version is going for £279. They are expected to sell out rapidly so you'll have to be quick.
