I spent an hour or so on Friday evening messing around with my Nokia
N95. Backed up the date, updated the firmware from v11 to v12.0.013.
Only to read today that an even newer update (v20.0.015) has
appeared...

So it looks like I'll be updating again soon, and quite what happened
to versions 13, 14, 15, 16, 17, 18 and 19, I guess we'll never know!
