Yes

Yes

thank you..but how and if we haven't sync to a new computer yet

1. Sync to a computer

2. When it asks if you want to update, say "Yes"

Even inactive sims will activate a GSM iphone and let you into the homescreen.
As long as the sim is from the carrier the phone is locked to.
If its unlocked any simcard will do the trick.
