Should I unlock to avoid AT&T activation when upgrading to bigger iPhone?

[superspiffy]

What should I do if I want to upgrade from an 8Gig iphone 3G to a brand new (unactivated) 16gig iPhone 3G if I don't want to go through AT&T's activation process? Should I use yellowsnow or quickpwn to unlock the 16gig and swap the 8gig's SIM to it?

Just put the SIM in it without doing anything, should work fine. I would assume so.

Are you assuming that the new iPhone is already activated or not ?

Well, when I got an AT&T refurb as an early upgrade (this just happened on Dec 31st), I had my old iPhone's SIM card with me. I just plopped it in and it worked.

It came with a SIM already but as much as I tried to activate it with that one (and I really didn't know how because iTunes didn't give me any directions to) it wouldn't work. I'm sure that if I had an iPhone 3G plan currently I wouldn't have had to call AT&T so they could do whatever they needed.

I had the original iPhone plan because [insert here a REALLY LONG story about having an iPhone 3G and a lot of stuff happened], and then they sent me a text and email saying I had to go to the 3G plan and had to call them.
