According to Boy Genius Report, they received some evidence of iPhone OS 4.0 in the wild from their “trusty Apple connects”.

Here are some iPhone OS 4.0 features according to Boy Genius Report:

• There will be multi-touch gestures OS-wide. (Would make sense for that as the rumored OS for the iTablet is close if not the same as the iPhone)
• “A few new ways” to run applications in the background — multitasking.
• Many graphical and UI changes to make navigating through the OS easier and more efficient. We haven’t had this broken down, but we can only hope for improved notifications, a refreshed homescreen, etc.
• The update will supposedly be available for only the iPhone 3G and 3GS, but will “put them ahead in the smartphone market because it will make them more like full-fledged computers” more than any other phone to date. Everyone is “really excited.”
• The last piece of information is the most vague, but apparently there will be some brand new syncing ability for the contacts and calendar applications.

Apple is expected to announce or talk about iPhone OS 4.0 at their event next Wednesday.

Here are three ways to boot Mac OS X Snow Leopard into 64-bit kernel and extensions. Please note that not all Mac computers support 64-bit. Here is a list of Macs that currently can boot into 64-bit mode:
