The best review for the 3G SIM card is the AT&T 3G SIM card. The newest 3G Wireless SIM card is the best and only costs $7.85. There is also a AT&T SIM card for $3.85.
yes they do all have sim cards also on a different note the t-mobile phones accepts the cingular sim cards when unlocked and vice versa
Verizon doesn't use SIM cards, so the Verizon iPhones presumably don't. All AT&T iPhones have a SIM card, though.
the AT&T network, and the T-Mobile network both use SIM cards I know that Nextel and Sprint also use sim cards.
All carriers handle SIM cards differently. AT&T requires SIM cards, but Verizon does not use them at all. Check your carrier's website for specific information.

As AT&T is a GSM service provider all of their devices require a SIM card to operate on their network
all iphones have a sim slot but on the original iphone the customer cannot easily access it whereas the 3G iphone has the sim card and a sim card ejector tool How can I access my verizon iphone 4 sim card slot that doesn't have a sim tray
yea i have gotten several phones from att and used the same sim card for all of them, and kept the same phone number.
Yes. AT&T stores carry SIM cards.
Yes, but only if you unlock you iphone
Buy a SIM Card from AT&T or T-Mobile called a Micro-SIM. These will fit in the iPhone. Apple is planning on using Nano-SIM Cards which are even smaller.
