Here are some highlights from the Apple iPhone 3.0 software upgrade I found today (thanks to Gizmodo)
• Copy & Paste photos. You can also copy and paste photos. Now you will be able to select multiple photos by tapping the action button, copy some of them, and paste them in an email, ready to send.
• New Spotlight. iPhone OS 3.0 will allow you to search across the entire information contained in your device, no matter where, as soon as the information is supported it. If an application is written to support the new Spotlight, its data will also be available in the search.
• Search in Mail, Calendar, and iPod. These Apple applications have specific search interfaces. The search in Mail doesn't support the message content yet, but it supports searching in IMAP servers—that will save a lot of time logging into Gmail.
• 3G Tethering. (My personal favorite) This feature will allow you to connect your iPhone 3G to a laptop, to use it as a modem to access the internet. Carriers still have to sign-off on it, and probably charge more for it. None have announced it yet.
• Multimedia messaging. A big one to send rich content to people without mail-enabled telephones: The new MMS function will allow you to include everything, from images to sound to vcards (no word on video, however.) Personally, I find these usesless having email, but some people seem to want it.
• Shake to shuffle music. If you are in your iPod application, you just need to shake it to start the shuffling mode. Hopefully this will be optional for sports people out there.• Turn-by-turn directions. Developers will also be able to create turn-by-turn applications using the GPS information from the iPhone and combining it with their own maps, without depending on 3G connectivity or Google.
*iPhone OS 3.0 will be a free upgrade to all iPhone users, including the first generation (not all features will be supported in the first generation, like Stereo Bluetooth support). iPod touch users will be able to but it for $US 9.95.
