I currently have an iphone 3gs and I cant upgrade till next year but I plan buying an AT&T iphone 4 from a friend or on an auction website next month, how do I transfer my sim card onto the iphone 4? Will I have the same number and can I transfer my contacts? Plus it won't renew my contract or anything will it?

You can go into a corparate AT&T store and ask them for a new SIM card for your iPhone 4 on your account. Thye may charge you $20-30 for it, or you may just get one for free. This is the easiest way to get the right SIM card for an iPhone 4 on your account. If you aren't willing to do that, and you have an existing iPhone 4 SIM card (just not on your account) they you could use it as a template to mark your existing SIM card and cut it down. I have done that with one SIM card, and it works just fine, but I don't recommend it if you don't have an existing SIM card to see exactly how it should be trimmed, and even then, I'm not sure I would recommend it, but I do know it can be done as I have done it myself (well, I trimmed a SIM from a Blackberry Bold down to use in an iPhone 4).

It shouldn't. You already have an iPhone and an existing contract with AT&T, right? As far as they are concerned, you are just getting a replacement iPhone (from Apple or from from other outside source). As long as you aren't changing your voice service, data plan, or anything else related to your monthly billing, AT&T shouldn't see this as an account change and renew your contract.
A few years ago mi wife moved her SIM card form her Blackberry Bold to my old iPhone 3G, and the onlything that AT&T did was to change her account so that the data service would work on the iPhone. No charges from them, and no contract changes, so that when her contract was up 2 months later we bought her an iPhone 4. When that iPhone 4 got dumped in water last month, we put her SIM card in my old iPhone 4 and AT&T didn't change her account and now that she contract is about up we are about ready to go get her a new iPhone 5... Funny how her phones seem to die right before her contract, and my old phones which have beeen out of contract about 6 months are still working fine to carry her over until she is eligible for an upgrade...

On the subject of transferring your contacts, do a backup of your 3GS, then restore from that backup on the iphone 4.

And one last thing, I would still have the same cellphone number correct?

Like a previous poster said back up the old phone and then restore the new one using the old phones backup.
