Mobile World Congress 2011 is now just a memory, but that doesn’t mean you have to miss all of the events from the final day on Thursday -- our friends at TechRadar were there in full force, and here’s a quick rundown on all of today’s news so you don’t miss a single thing.

Nvidia previews quad-core Tegra 3 for late 2011

Hands on: CoPilot Live 9 review

In the battle for GPS navigation dominance on mobile phones, ALK’s CoPilot Live is a formidable opponent. TechRadar took some time out to see what’s new with the latest CoPilot Live 9.
