Got the discounted pricing on the 32gig 3GS. I currently have the 3G and she has a 2G. Want to confirm exactly the process for swapping the SIM's. The phone is being shipped from the online Apple store: 1. Do one last sync with Itunes so everything is current on both accounts 2. Open the 3GS Here's what I need to confirm: Do I? 1. Swap the SIM cards and then re-sync with Itunes? My wife is taking the 3G or 2. Have her activate through Itunes first and some of her content will synch and then change out the SIM cards? Researched the forums and seen both processes.
