[solved] Add APNs (access point names) to android system database
The access points database for Android 4.1 is in
Talktalk / talk mobile provide information for APN here:
However, the information they provide is false. Username and password must be unset.
I added the following before </apns> at the end
The phone will now give an option for TalkTalk APN, which I just need to select.
Now it is a matter of committing this entry to the official android repository. Of course, whilst I was at it, I replaced the whole apn database with the one from the Android repo.
