There are probably more than a few of you thinking about selling off your old 2.5G iPhone in order to make some room in your bank account for the new iPhone 3G. Unfortunately you'll discover that there is no good way to securely erase all of your personal data from the phone, not yet at least.

This oversight is one that Apple intends to correct with the new iPhone 2.0 update. When you finally have the new software (which likely won't be coming out until the iPhone 3G launch happens on July 11) you'll be able to safely and securely destroy all of your private data. Think of it as the phone equivalent of your Secure Empty Trash on your Mac.
