Last week, Apple announced the impending arrival of iPhone 3.0 software, an update to the iPhone OS to be released this summer (along with, probably, a third-generation iPhone).

So what's exciting about the 3.0 OS? Believe it or not, one of the most talked-about features added is the ability to cut/copy/paste - functions that were noticeably absent from the iPhone but available on competitor products like the Blackberry.

But beyond cut/copy/paste, OS 3.0 also offers a search function, expanded MMS abilities, peer-to-peer Bluetooth between iPhones and nearby iPod Touches, and what could be really significant for many people: hardware APIs that might let people use an iPhone to check blood glucose or blood pressure levels, for example, and transmit the info to a parent or doctor.

Also, some guy supposedly figured out how to get his iPhone 3.0 to tether to his laptop, providing an Internet connection, but he promptly forgot how. Oops. Stay tuned - I'm sure it won't be long til someone else figures it out.
