I didn't get mine insured - I figured it'd be covered under home insurance. The one time I did get phone insurance (not through O2 I hasten to add, Singlepoint's one or something like that), I paid £7.50 a month only to find that when my phone did get stolen, they refused to pay up, even though I had a police report and everything. Since then I've always been *very* dubious about mobile phone insurance. It always seems so expensive when compared to home insurance.
