@mpt, right, I was confused when I reported the bug, and thought that the "Manually"
The APN is a set of configuration data needed to open a cellular data connection. This data is operator specific, but not network specific. That is, the data depends on who you pay at the end of the month, not on the network you are registered in at a given moment. Specifically, the APN does not change when you are roaming and you are not connected to your home network. Operators connect to each other so when you open a cellular data connection the APN data travels through the visited network to your operator so it validates it.
As the APN data is static you should be able to edit it whenever the phone is powered and has a SIM card (even if you are not registered in any network at that moment), as with the data on the SIM you can know who is your operator.
