Finding iPhone OS 3.0's small changes

Though everyone knows the iPhone OS 3.0 brought welcome and long-awaited changes like multimedia messaging; a landscape keyboard; and cut, copy, and paste, there are a host of other tweaks from the software update that Apple has not publicized. According to Apple, the update offers 100 additions to the iPhone, but we covered just a handful in our iPhone 3GS review.

What other features are new? Well, a week after Apple released the update to the world we have a better idea. We've done our own exploring, but last week we also asked for your help in finding the update's hidden treasures. Thankfully, you responded in force, so we're glad to offer you this list. It's still not complete, so we'll be adding more as we (and you) find them. (Note: I've only included features not listed in the review.) Also, Apple has posted a handy chart detailing which OS 3.0 features are available on the iPhone Classic and iPhone 3G.
