Are there any password managers for iPhone and Windows XP?

Currently I use KeePass on my PC, an free open-source software on Windows to manage passwords. The iPhone version of KeePass is not available yet, but it is in development.

An existing commercial product for the iPhone is Iliumsoft's eWallet. It has some nice features like synchronization to a desktop PC version of the software. Besides usernames and passwords, you can also use it for storing other sensitive information.

Wanting to upgrade my current three-password method (basic, secure, and super-secure), I spent this evening researching this very topic. I wanted something that worked well with Firefox on my PC and Safari on my iPhone. I ended up deciding that there wasn't a sufficiently good solution. Here are the candidates are here's why I don't like 'em:

KeePass: Highly-regarded open source password manager, works with Firefox. Doesn't yet have iPhone support. Supposedly will have iPhone app Real Soon Now.

eWallet: Seems good, but costs money on the iPhone and PC, plus no Firefox support.

SplashID: Seems good, but costs money on the iPhone and PC, plus no Firefox support.

1Password: Seems perfect, has a clever bookmarklet solution for auto-filling on the iPhone, but is Mac-only (and costs money).

LastPass: Seems great, almost perfect, but stores your passwords on their server. Also seems to have cool bookmarklet feature, but this only works on the Mac. Came closest to persuading me.
