What will happen if I insert my 1st Gen iPhone sim card into unlocked iPhone 3GS? I turned on the 3GS iphone’s 3G network, it showed the “3G” icon on the left up corner, and the internet worked perfectly. I have the 1st Gen iphone contract, if I dont tell AT&T, will AT&T find and charge fee for the 3G network function? Thanks!

I dont think it matters, i’ve had the same sim card for years, i had it originally with a RAZR, they just took it out and stuck it in my iphone… end of story.

Your sim card works fine in the 3G S but soon AT&T will notice that you are using 3G and will spam text you until you call to update the plan to a 3G plan.

It will tell you to connect your phone to itunes to activate it.
