4G LTE iPhone 5: Carrier Settings Update never came

Hello,

Just to say, before I start: This question is related to Switzerland's Swisscom's 4G LTE network and iPhone 5.

I have updated to iOS 6.1 (for Swisscom 4G LTE compatibility, it's now compatible), but didn't get the carrier settings update, and when I reset the iPhone (including erase all content), I got the Carrier Setting Update and it enabled 4G LTE, but I have progressed in lots of apps and games (mainly apps), and it will be very difficult to do a full restore and recover all my progress etcetera. How can I get the Carrier Settings Update? I went to Swisscom, and they said to erase the iPhone, but again this would be a big inconvenience and I am trying to avoid it.

Sorry about any problems: I'm not very tech savvy with iOS devices, and this is my first post here so I may have put in the wrong section.

Thanks a lot in advance
