Bluetooth 4.0

[brettlewis]

With bluetooth 4.0 being officailly released soon, will our phones bluetooth be upgraded?
It might be a stupid question, I just dont know if the upgrade is software based or a hardware upgrade?
From what I have read, it is very energy efficient and could be a big boost in battery life for those of us who use bluetooth frequently.

Thanks!

If it's a SW only upgrade, then it's possible...however, Google has shown precious little interest in bluetooth, we still don't have BT dialing, so I'm not going to hold my breath.

I'm pretty sure that it's hardware based.....actually yea it definitely is.

It would have to be strictly hardware based... every version of bluetooth is faster than the former. That means that it is similar to upgrading your wireless between 811b/g/n.

Bluetooth v4.0

On June 12, 2007, Nokia and Bluetooth SIG had announced that Wibree will be a part of the Bluetooth specification, as an ultra-low power Bluetooth technology.[26] .


On December 17, 2009, the Bluetooth SIG adopted Bluetooth low energy technology as the hallmark feature of the version 4.0.[27] The provisional names Wibree and Bluetooth ULP (Ultra Low Power) are abandoned.


On April 21, 2010, the Bluetooth SIG completed the Bluetooth Core Specification version 4.0, which indludes Classic Bluetooth, Bluetooth high speed and Bluetooth low energy protocols. Bluetooth high speed is based on Wi-Fi, and Classic Bluetooth consists of legacy Bluetooth protocols.
