Apple have announced their feature rich firmware upgrade for the iPhone, here is a quick list of new features, see link below for full story-
• Copy & Paste text. When you double-tap over text, you will get a “cut, copy, and paste” bubble dialog. Double-tap again and a “paste” bubble will appear if there’s anything stored in your clipboard.
This works across applications. You can expand your selection points using your thumbs and, if you accidentally paste something you didn’t want to paste, just shake your iPhone to undo it.
• 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. This feature will allow you to connect your iPhone 3G to a laptop, to use it as a modem to access the internet.
• Landscape keyboard. Apple has added the landscape keyboard mode to other applications, like Mail and Notes.
• 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.)
• Support for new calendar types. In iPhone OS 3.0 you will be able to subscribe to calendars on the web using two protocols: CalDAV—supported by Google and Yahoo—and subscriptions via the .ics format—which is what Apple uses in iCal.
• Improved stocks application. The stocks application now allows you to read related news, so you can enjoy yourself learning about the latest market scandals, stock crashes, and executives getting bonus packages from government aid while their companies sink into hell. Thank you, Apple.
• Stereo Bluetooth audio. You will be able to pair your iPhone 3.0 with a stereo bluetooth device, like headphones or speakers.
• Note synching with iTunes.
• Automatic login in Safari. The new version of Safari will remember login credentials.
• 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.
• Wi-Fi auto-login. In case you have a subscription to a paid hotspot, your iPhone or iPod touch will autolog into it.
• Anti-phising. Mobile Safari now can warn you against malicious sites trying to scam you.
• Extended parental controls. Adult content filters can now be applied to movies, TV shows, and applications, in addition to web sites and music.
Update scheduled to be released in US summer..
