Just trying to see how I can erase this iPhone before I get rid of it. It has 2.0 software on it. Searched on Google and got this: http://support.apple.com/kb/HT2110 It says that with the iPhone 2.0 software that when I "tap Settings > General > Reset > Erase All Contents and Settings, iPhone OS will remove all contents and settings by writing ones to the data partition." Is this sufficient enough to ensure that my data cannot be recovered? I just don't want this to happen to me. Thanks in advance.
