New firmware 1308.0006 in Switzerland

[Tomanband]

My Lumia 920 on Orange Switzerland just notified me that there was a "Nokia update" for my phone, the version number changed from 1308.0004 to 1308.0006!

Does anyone know what's new?

EDIT: It enables 4G, since the network launches on the first of June here in Switzerland!

That good have you gone to 4G or still with 3G and was there any other features or improvements with the update?
