Does iPod Touch 4th generation support Bluetooth LE?

Question

I'm just wondering if iPod Touch 4G supports Bluetooth 4.0 with Low Energy. Bluetooth LE (BLE) for iOS is supported for iOS v5.x. So does upgrading to iOS 5.x enables BLE for iPod Touch?

Sometimes manufacturers use advanced hardwares to make sure they are compatible with future technologies. On the same lines, is it possible that Apple must have also done the same, envisioning that BLE will be part of iOS v5.x?

Answer 1

iPod touch 5th Gen and iPhone 4S and iPhone 5 and some concurrent iPad, lost link to which one all support BlueTooth LE.
