[2008.12] sim card problems

[Robin Paulson]

i've had some intermittent problems with text-messaging on my fr,
using the qtopia messaging app. at some points, if i try to delete a
message, i get the following error:

'SIM card is not ready, are you sure you want to delete this message?'

i can't remember the exact text, but it's something close to that.

what's happening here, i.e. why is the sim card not 'ready' (whatever
that means), and what will happen if i do delete the text?

sometimes it's fixed with a reboot, sometimes not
