1Password is a free program that is appeared very quickly after the opening of the AppStore. 1Password can store passwords and other confidential data in a secure area protected by a password on your iPhone/iPod Touch.
The software is available on the iTunes Store until December 1 for $0.00 .
Remind that it is extremely dangerous to store passwords and other confidential codes in the application notes of the iPhone, which can be accessed by anyone if the iPhone is ready and worst lost!
So enjoy the free and I likes this software.
