After a hard reset...

[speck]

I'm sorry if this is a really basic question, but what's involved in a hard reset?

I know HOW to do it, it's what to do to get my phone back as MY phone again that I don't know.

I got it at Best Buy and the guy there did all the initial setup. What things do I need to know (besides my phone number of course) to enter after the reset? I found my MEID, MDN, and MSID - will that be the information I need? (and what are those numbers anyway?)

I'd feel a whole lot better changing the registry if I knew I could always get back to square one!

Thanks to all of you - I think I would have returned my TP day one if it wasn't for all of you. I know this phone has great potential, and knowing that people are working on exploiting that potential is helping my learning struggles - I know it'll be great in the end.
