And now I have no connection to the internet – I can still make calls and SMS but no data connection. I’m on Vodafone’s $49 cap plan with 1.5GB of data (should be plenty!) but there’s no 3G sign or anything when I turn of my Wi-Fi! I called Vodafone and they said it was not their coverage problem.
If you have any tips or advice, please let me know!

This could be a problem with improper activation at Vodafone’s end, or otherwise a problem with your carrier profile. If you’ve absolutely exhausted all options with regards to resetting settings, restoring to factory defaults and, of course, talking through the problem with Vodafone, I advise getting on Wi-Fi and visiting the following URL from your iPhone: www.unlockit.co.nz
This crew provide custom carrier profiles (otherwise known as APNs) for iPhones, catering to a wide variety of international carriers, and I (as well as many, many others) have had success treating a wide variety of esoteric and improbable problems of a similar nature to your own by deploying a custom carrier profile.
Simply visit the website from your device and follow the on-screen instructions to install the APN for your selected carrier.
Reader beware. Custom carrier profiles can be unpredictable, and a wide variety of problems can potentially come from using them, including, for instance, your Wi-Fi spontaneously deactivating or your 3G coverage dropping out significantly or even entirely. Should the profile be defective, however, swapping back to the original is as easy as going to Settings > General > Network > Cellular Data Network and switching over.
