Do i need to get a new sim after returning my iphone 4 to activate 3gs?

[puggles]

I thought 16GB would be enough but its not now that i have Navigon and HD videos are taking up a ton of room. Im going to return my Iphone 4 and wait until the 32GB white becomes available but how will i use my 3GS in the mean time?

At&t will also swap it back at no cost. Then, when you activate the 32gb, the microsim should be active again.

AT&T will give you a new SIM when they deactivate your 3GS they did for me and reset my upgrade eligibility back you will be ok
