If I change SIM card, does Goog Account need reset?

if I change to a new SIM, do I need to reinput all my account info?
Gmail, market, etc all that stuff?

When I put a new SIM card is, to test the unlock I did, I had to re-enter my Gmail password. I did not need to re-enter my Facebook or Email info (Yahoo).

Ironically, when I did this, I also lost the contacts that must have been setup as T-mobile sync contacts, even when I put the T-mobile SIM back in. I have since turned off T-Mobile sync and sync everything with Gmail.
