The white version of the Google Nexus 4 was officially announced last Tuesday and it has already been made available for purchase on the Google Play Store in the U.S.. Previously the device was expected to arrive on June 10th, which is the same day Android 4.3 Jelly Bean was rumored to roll out.
The handset can be purchased for the same $299 and $349 on the Play Store but Google is sweetening the deal by including a free bumper along with your purchase.
The white Nexus 4 features the same hardware as its darker sibling including, a 4.7 inch HD touch display, up to 16GB of internal storage an 8 megapixel camera capable of 1080p HD video capture and a quad-core processor with 2GB of RAM.
The white variant of the Google Nexus 4 is also available through T-Mobile and costs $19.99 down with 24 equal monthly payments of $17 for well-qualified customers with 0% APR on approved credit. That totals to $427.99, so you would probably prefer the cheaper Play Store option instead.
