how do I find out if my Bluetooth dongle suports version 4?
does hciconfig -a hci0 show this?

Re: how do I find out if my Bluetooth dongle suports version 4?
According to this the commercial name for the main feature added in Bluetooth v4 is Low Energy or LE. If the specs for the device don't indicate Bluetooth version, maybe they mention LE.
OTOH as indicated here you should be able to get more detail about features by running hciconfig -a hci0 features . In the output shown on the askubuntu question is "<LE and BR/EDR>". It's just a guess since we have no idea what device was involved there, but it seems reasonable to assume the LE stands for Low Energy and thus indicates it's a Bluetooth v4 device.
But whether the Constitution really be one thing, or another, this much is certain - that it has either authorized such a government as we have had, or has been powerless to prevent it. In either case, it is unfit to exist.

thanks. LE suport should be it, since version 4 is Bluetooth LE.

Just to add to the muck, the Bluetooth 4.0 specification defines BLE, *but* a Bluetooth device can be Bluetooth 4.0 compitible WITHOUT supporting BLE -- it is optional 
Nothing is too wonderful to be true, if it be consistent with the laws of nature -- Michael Faraday
Sometimes it is the people no one can imagine anything of who do the things no one can imagine. -- Alan Turing

Oy, the page I linked even indicated that pretty clearly. Talk about missing the forest for the trees...
