I got the update for Cyan on 1520 CV GBIE and one thing I noticed was that in network I only have the option to choose 3g or 4g. What happened to 2g. I ask this because I on 8.0 and when i had the dev preview of 8.1 and I could choose 2g but now with cyan update I can't. Any one else have the same issue, and it?s from UK? Also i contacted my network wich is Vodafone Portugal and they told me that is nothing to do with the network but firmware bug.
