While it certainly wasn’t the most consequential revelation from yesterday’s WWDC keynote in which Jobs, of course, introduced the iPhone 3G, the App Store, MobileMe and more, the iPhone 2.0’s scientific calculator could prove quite beneficial for mobile learning initiatives.

In iPhone 2.0 users will be able to rotate the standard calculator to landscape mode for a scientific calculator, which offers all the functions you would expect from your old TI-85 including squares and square roots, sin, cos, tan and factorials.

Perhaps the new sci calc won’t be the feature that sends people running to pick up a new iPhone (which, at $199 for an 8GB, will certainly be a significant number of folks), but the added functionality will be a nice bonus for those of us using the device as a tool for teaching and learning.
