PasswordWallet 4.4.10 for iPhone is available in the iTunes store with lots of great new features! An Express Clipboard screen lets you paste your username in to the Safari browser and return quickly to copy your password. Digits are now colored red so you can distinguish between O (Oh) and 0 (zero). And PasswordWallet shows the keyboard the moment you launch it so you can enter your master password right away! That problem with the section index is also fixed. It just plain works better now.
PS - PasswordWallet is no longer rated at 17+ on the AppStore, and has a nice, family-friendly 4+ rating. Thanks, Apple!
