Thanks for the tip on the SIM card remover, one of those with some gentle (ish) tapping with a small hammer and I was able to get it sorted.
How do you guys store yours? I've got them both kinda crammed in the box but it's not the most elegant solution.
I wouldn't mind knowing a bit more about the Esprit too, but as far as I can tell they don't keep info on old models on their site and this is from 2006.
