Public bug reported:

I have two mako devices, one running devel, one running devel-proposed.
Normally my devel phone is my main one and is mostly used on wifi. I
took my devel-proposed phone out on saturday and it was unable to
connect to 3g at all.

Note: I had swapped SIM cards (both same network) between the two
devices, so my proposed phone had my main phone number on it.

When I got home I've done some looking and found some debug info in bug
1335165.

I saw this in the syslog.

My APN was set to mobile.o2.co.uk (which must have previously worked) but now 
no longer does? Or perhaps switching SIMs around reset the APN?

So to fix it I found the giffgaff settings at
http://community.giffgaff.com/t5/Settings-for-your-device/Internet-and-
MMS-settings-APN-guide/ta-p/3489121#faq_no_6

And issued the following:-

/usr/share/ofono/scripts/remove-contexts ; /usr/share/ofono/scripts
/create-internet-context "giffgaff.com"

I rebooted the phone and now it works.
