I NEED SOME SERIOUS Help... Question about Lost Phones and Security Codes

[wphend00]

Sorry to type in all caps...

I lost my phone on Sunday... I don't know how or wear...
I had one of those rubberized belt clips for my phone, the 2 piece ones with a front and a back.
Sometime between 3:00pm at church, and 5:20pm at home, I lost my phone. Somehow it was either pulled off or I clipped it on something. It would take a lot of force for anything like that to happen, but it did. When I left my house to go back to Church, I looked down at my belt, while I was pulling off in my car, and saw the back half of the case still clipped to my belt, minus the phone.

Blessing for me is that I had the code set on it, so no one can access it after 5 minutes...
And if they mess up the code, 8 times, it will kill the data on the phone.
the question I have, is will it wipe the Secure Digital card too?

I am hoping it does, but does anyone know this for sure?
