Argh no phone :(

Something seems to be screwy with my SIM card -- with it in, the phone freezes at the boot logo; with it out, it gets to the desktop, and I can access the service menu, but trying to do anything useful gets an "insert SIM card" message :(

It's suddenly occurred to me that I no longer have an alarm clock, a mobile calendar, a to-do list, a camera, a notebook, a mobile IRC client, or a games thing to pass the time in lectures. Not being able to communicate by phone or SMS is also a problem, but not the first thing that comes to mind...
