1. It's speedy
Leaving the Bluetooth we currently use eating dust, 3.0 manages to pull data transfer speeds of 24Mbps out of the bag. Considering we currently max out at 3Mbps, that's going to save a fair bit of time when you're winging stuff over from your phone to a mate's.
2. It's got cosy with Wi-Fi
You can thank 802.11 Wi-Fi for the extra skip in 3.0's step. The new Bluetooth takes advantage of the 802.11 radio protocol to give it the boost it needs to hit the higher speeds.
3. You get more Bluetooth for your battery life
Turning your Bluetooth off to stop it sucking the life out of your phone will be a thing of the past with 3.0, thanks to enhanced power control. This means you'll be able to leave it on and use it as and when you need to without worrying it'll leave you stranded battery-less. Much less hassle.
4. Send bigger files without wires
The extra speed that 3.0 packs means you're going to be able to whizz bigger files like HD video and music libraries backwards and forwards between your devices. This also opens up the doors to manufacturers to work on better tech to take full advantage of this capability. We like the sound of that.
5. We've got a bit of a wait
So now you're all excited about Bluetooth 3.0, we'll break the bad news. It's not actually going to hit end devices on the shelves for another 9 to 12 months, so we'll have to put up with our bog standard 2.1 for now. Still, we'd expect most manufacturers will jump on the bandwagon pretty sharpish so if you're in the market for a new phone around that time, you'll be pretty sure to get your hands on it.
