As many of you know there are tons of questions to be asked regarding iPhone upgrades. I have eliminated alot and now only have a few to ask.

As of right now I'm eligible for an 2 year upgrade. I am planning on selling my iPhone 3GS 16GB real real soon and Pre Ordering on June 15th. My questions are 1. Can I remove my Sim Card and use it in an 8GB iPhone 3G WITHOUT it messing up my upgrade eligibility from now until launch and #2. If I did put the sim card in an iPhone 3G or even a cheap GoPhone will it still keep my current $30 Unlimited Data plan? The reason I ask that is because I don't want to switch to the 2GB Data as I rather have the unlimited since I am a current iPhone user since 2007.
