Testing on iPhone device without SIM card

Question

I have an iPhone 3G that worked fine for development on iOS 3. I just updated to iOS 4.1.2, and Xcode Organizer tells me This device is not activated. Please activate it using iTunes. I've restored twice now.

iTunes tells me to insert a SIM to activate it—however, I don't want to activate it. This iPhone is for development only. The phone itself says "No SIM Card Installed. Insert a valid SIM with no PIN lock to activate iPhone."

How can I get the "please activate" message to go away so that I can use it for development?

Edit - I do not have a standard SIM card that I could put in temporarily. All I have is a micro SIM for my iPhone 4.

Answer 1

All you have to do is insert any SIM card, active or not, get the device set up, and then take the SIM card out. It should work fine from there (I use a no-SIM 3G for testing 4.2.1).
