iOS 6? Please head over here.
Have you ever looked at your carrier name in the status bar of your iPhone? Chances are you have. If you’ve ever wondered where this actually comes from – this is really just an image contained in the carrier’s bundle of settings.
This makes it much easier for this to be customised or changed. Carriers can (naturally) and do change how their network appears – Optus changed from ‘OPTUS’ in firmwares lower than 4.x to ‘YES OPTUS’ in iOS 5. Telstra choose to display ‘3TELSTRA’ as ‘Telstra’, (and likewise for 3 – choosing to appear as ‘3’ instead of 3TELSTRA)
This is also handy for users – carrier bundles are easily edited and tweaked by users and can be deployed semi-officially – the same way carriers can deploy themselves on the side.
While in iOS 5 many of the actual carrier configuration data is signed and will refuse to work if the signature is broken – the images are free rein. You can do whatever you want here.
