After upgrading to a new 3GS, my original iPhone won't activate...

After I upgraded to an iPhone 3GS, I restored the original iPhone with iTunes. Now, the iPhone says it's got an invalid SIM in it, and when I plug it into iTunes, it won't activate it. It's basically a brick now.

Was I wrong in thinking I could now use the old iPhone basically like an iPod touch?

Intel iMac, unibody MBPro, & iPhone, Mac OS X (10.5.6)

You can only continue to use your old iPhone EXACTLY as it was at the time it became de-activated. You can not upgrade the OS software at any point from there on, or it will look for a valid SIM card.

The solution here, which might be too late for you....is that you need to update to 3.0 on your old iPHone 3G BEFORE you then activate your new iPhone 3GS. Once you activate your new 3GS, your old iPHone SIm is de-activated, and you can no longer do OS updates on that iPhone.

I haven't seen any press release that supercedes that, but the one you reference refers to the ORIGINAL iPhone, not a 3G. There have been posts here and elsewhere indicating that the restore/upgrade function no longer works on the 3G once you update to 3GS.

I suppose the original poster can put a phone call in to AppleCare to see if they might be able to get some help from them. I didn't make this rule, I am just reporting what everyone else is seeing, with or without the SIM card in the 3G.

I don't know, but it's worth a try---I think I have heard other people mention doing that. And AT&T should be willing to give you a new SIM for the new phone. You might hold off on trying it until a day when you have time to go to AT&T just in case the SIM doesn't behave when you swap it back.

All I know is what the Apple KB I linked says, really.
