iOS 7.1 Released today and the iPhone APN Changer still works well. There are many changes between 7.0 and 7.1 but none of them directly affect how the website works.
Over the last few months I have added a large number of iPhone Mobile Settings for various Carriers around the world but I add more over time as people contact me to add them in.
If your Carrier is not listed please let me know and preferably a link to the Carrier you are using so I can look up the settings and add them in (or a link to them directly makes it easier for me).
There may be a mistake in a few but over all I believe 99% of the settings are correct for carriers.
I am also looking for more advertisers so if you are interested in advertising directly with a very popular iPhone related site please let me know as well.
