If you're not quite ready to take up ASUS on its refund offer (or if you simply don't live in the UK), you're probably holding out for additional updates to dry your tears. Fortunately, Asus hasn't forgotten about you and your ilk. Early this morning, the Transformer Prime quietly received an OTA update that not only unroots the tablet, but also kicks the slab's GPS version up to 6.9.13. The folks on the XDA developers forums have restored their roots easily enough, and seem to be reaping the benefits of updated GPS drivers, as well. Engadget's own tests lean on the positive side -- lounging indoors, in a spot where GPS reception was previously all-dark, we snagged sight of 12 satellites on a freshly rebooted Prime with WiFi disabled. Although the response seems generally positive on the XDA developers forums, not everybody is seeing our success. Either way, this update certainly didn't make things worse; a step in the right direction to be sure.
