Swapped SIM from iPhone ineligible for upgrade to one on account that was.

[Cru Jones]

The primary phone (iPhone 3G) on my account was ineligible for an upgrade, but one of the other (non-iPhone) handset was eligible. When my new iPhone 3G S⃣ arrived, instead of waiting for up to 48 hours for activation, I made use of the included SIM Card removal tool (save the paper clips!) and simply swapped out the card in my 3G for the one in the new 3G S⃣ . From there, I simply restored from backup, and viola!, I'm up and running! Has anyone else tried this and or had any negative experiences resulting from it? My apologies if this is a double post, but I couldn't find any specifically for this topic.

I have a friend who's had the exact opposite experience. His phone appears to be tied to the phone number he ordered it using, even though he swapped SIM cards. He can't restore or activate.

Has anyone else had success doing this?

So far, everything seems fine with mine. I even have the camera button in MMS from the hack I did on my old iPhone, but they don't send.
