I am glad I don't have to worry about the 'getting caught' factor. Even if you delete everything, there are still records. It's fairly easy to get into someone's wireless account and look at the records and many of those numbers can be googled up in a jif.

Regarding phones: As others have stated in the thread, with the availability of prepaid phones out there today, there's really no reason to use your personal phone for hobbying. Keep your hobby phone off and locked at work and your SO won't find it. Don't you think it'll be more of a pain in the ass if you run into an unscrupulous provider and now she has your personal #? Try explaining to the SO why you need to change your number?
Also on a side note, my phone has learned the word "hobbyist". Damn you AutoCorrect!
