We had flagged up the imminent arrival of the white Nexus 4 just a couple of weeks back, although its arrival has been rumoured for months before. Now it is here, but not without a shade of disappointment.The new take on the LG-made Google phone has made its debut, but without the expected OS upgrade to Android 4.3. That was always rumour though, never confirmed by either LG or Google. So we can hardly blame either company. But it doesn't stop us from feeling a bit down about the launch.What we do have is a Nexus 4 with white back and black frontage and everything you would find on the standard black version. You can read our review of that here or take our word for it that the phone offers a 4.7-inch True HD IPS Plus display with 1,280 x 768 resolution and Gorilla Glass 2, a Qualcomm Snapdragon S4 Pro dual-core processor, 2GB RAM, an 8-megapixel rear camera plus 1.3-megapixel front camera.The price is presumably the same too, starting at £239 SIM-free. It will be available first in Hong Kong, then go on sale across the world in coming weeks.
