I have an iPhone 3GS on AT&T. My wife has an original iPhone, unlocked on T-Mobile. When iPhone 4 comes out later this month, I'm going to port my wife's number to AT&T. She doesn't care about the latest and greatest, which works out great for me. I'll carry the iPhone 4 and give her my year-old 3GS.

A year ago, this would've involved a simple SIM swap. Now that the new phone uses a micro-SIM, how do I do this?

Will AT&T care which of us has which phone? I'll certainly have to involve them to get my number married to the micro-SIM and her ported number on my current SIM.

Is this likely to suck as bad as I'm fearing?

Thoughts!?

Cut the SIM down to microSIM size. Seriously.

Cutting down SIMs to micro-size doesn't always work. In my experience, AT&T is usually quite cooperative in this sort of thing-they still get a new iPhone subscriber, right? It can't hurt to ask them before you take an unreversable step.
