Does having to re-input certain APN settings after a wipe or ROM flash drive you nuts? Thanks to XDA Senior Member CarpeNoctem, this is now a problem of the past. APN Generator allows the user to generate an XML backup containing all APN data. After this, you can easily export your data, as well as import your data after a ROM flash or full wipe.
CarpeNoctem is also compiling a database of all known APN settings. However, the database is not yet complete and probably will always be a work-in-progress. For those interested in helping to compile this list, the developer will share another XML structure for you to use to share your APN settings.
If you are interested in this tool or just want to help by uploading your APN settings, visit the original thread. Don’t forget to thank the developer and others involved with this project.
