Well, that's it. As of this morning, mobile phone #2 is done.
(For anyone who needs to get in touch - it still works for text messages either way, but the microphone is busted so it won't work for calls. My desk phone here is the office is also not working, so if it's really important then send me a text asking me to call you back.)
Unfortunately, this raises something of a quandary: should I buy another very basic mobile phone, on the grounds that I only ever use it for texts and a very occasional call; or has the time come to investigate and then invest in a smartphone, on the grounds that I'd almost certainly use more if it was available?
I'll update once I have a new phone, which should be soon.
