Good luck with stealing information from my phone... I think it holds about a dozen numbers. And a few text messages (mostly towards and from my mother, asking when she'll arrive or announcing my arrival).
My PDA holds a bit more information, like my phone number and address. And a few more addresses in my address book (as it synchronises with Outlook). Again, nothing more than you can find any any phonebook.
And bevdeforges, I'd probably hit them on the head with my phone. I know my phone will survive
