iPhone 2.0 software securely erases user data

[wraggster]

The fact that the iPhone doesn't securely erase user data when you select "Erase All Content and Settings" has prompted a lot of hand-wringing (and given rise to a lot of complicated manual workarounds) as people get ready to flip their old phones and upgrade to the iPhone 3G, but it looks like there's a simpler solution coming: AppleInsider says the iPhone 2.0 software now securely erases user data. The process is apparently similar to Leopard's Secure Erase Trash feature, and it'll unlink data and overwrite it with random bits, making your personal info impossible to recover. Of course, that'll take some extra time -- you're looking at an extra hour of progress bars in your life. That's not so bad -- and if it keeps anyone from checking out our super-embarassing 80s pop playlists, we're all for it.
