Still nitpicking further,

>All iPhones up to and including 3GS use standard SIM cards.
= Form Factor 2 (FF2)

>All iPhone 4s and iPads use the newer MicroSIM cards.
= Form Factor 3 (FF3)

Both are standardised, just like the old credit card-sized FF1 SIM.

Be careful if you need to insert an FF2 SIM which has also got MicroSIM FF3 dual punch-out to a phone that needs FF2 SIM. Some of those dual punch-out holes might jam the card interface quite badly. Compatibility problems of the transition period :-(
