From the commotion in the last several days/weeks I understood that a fake cell tower intending to play man-in-the-middle uses a 2G connection to avoid the authentication requirement (of the network towards the phone) that's part of 3G and up.
I would like to avoid such MITM attacks by turning off the 2G support altogether. I can live with it if my iPhone only uses 3G/4G, and refuses any service when only 2G is available.
I am using an iPhone 5S with IOS7.
Is there any setting or app I can use for that? (Preferably without jail-breaking my phone, but I know that might be a stretch.)

Very simple; No way Apple will allow you to do this
