Apple this week is holding its Worldwide Developers’ Conference, and has made several noteworthy announcements.

• The iPhone 3.0 software will be released on June 17. This will be a free download for current iPhone users.
• The new iPhone 3GS will be released on June 19. It will have a faster processor and some additional features like voice-dialing, video capture, a better camera, better battery, compass, and will come in 16 GB ($199) and 32 GB ($299) versions.
• The 8 GB version of the iPhone 3G will continue to ship, but for $99.
• Tom Tom will have a turn-by-turn GPS app available for the iPhone this summer.
• Apple has released new MacBook Pro models. The new versions are faster, have better batteries, more RAM, and come with 13″, 15″ and 17″ screens. They are also less expensive across the board. (However, they do away with the ExpressCard slot in favor of an SD card slot.) The new laptops are apparently shipping now.
• The next version of the OS, 10.6 (Snow Leopard) will be released in September.
• The next version of Safari, v.4.0, is available now through Software Update.

Because of the new MacBooks, there is reportedly a backlog of the previous versions that are essentially on sale. Check your local and online retailers to see if you can get a good deal.

Also, AT&T (who subsidizes the iPhone) will only let current owners upgrade after 18 months. Until then, the phone will cost $200 more for each model unless you’ve purchased one pretty recently.
