Sprint will start limiting mobile hotspot use, when a phone is turned into a Wi-Fi gateway, to 5 GB for both current and new subscribers starting 2 October 2011. Additional gigabytes cost $50 each, billed by the megabyte. Sprint is the last U.S. carrier to offer true unlimited 3G service, which remains available for on-phone data usage — for now! follow link
Copy Disk Image as Folder
When you open a .dmg file, a disk image is mounted. You are then generally supposed to copy the contents of that disk image to your hard drive (to your Desktop, your Applications folder, or wherever). But what if you want to copy the whole disk image, including all its contents, as a folder? Hold the Option key, and drag the "proxy icon" in the title bar of the disk image window to the destination in the Finder.
