Engadget has gotten their hands on iPhone firmware version 2.0. Some of the new features include a scientific calculator when you turn your iPhone sideways with the calculator open and the previously announced Exchange support is as smooth as it should be.
If for whatever reason you wish to know what version your iPhone is but are not really sure, just read this and it will provide you with some quick help.
1) Press the Home button
2) Then press the Settings button
3) Now press General
4) Now go to About
5) Look for “Version:” after that, it will have a bit of text, but we are only interested in the first 3 numbers, it will say something like 1.1.2, 1.1.3. If yours says 1.1.2 you have firmware, same deal with if it says 1.1.3 or something else.
Enjoy!
