3GS SIM and Plan to Iphone 4

[BCC4321]

Hey everyone,

I've been a long time lurker and hope you guys will be able to help me out

I have an iPhone 3GS and will soon be purchasing an iPhone 4. My question is, will I be able to use my current SIM card and the plan associated with it, with the new iPhone 4?

Why not just transfer everything to the new sim with iPhone 4?
