Zimbra has announced mobile account access to iPhone users via it's new web service front-end called iZimbra. Zimbra, for those of you unfamiliar with the product, is an open source messaging and collaboration solution that is what one might describe as a Microsoft Exchange clone, offering the same functionality and collaboration exchange as Microsoft's proprietary corporate communication suite.

What iZimbra does is basically bring something very similar to OWA (Outlook Web Access) formatted to iPhones's mobile browser.

I've always been very curious about Zimbra and it looks extremely promising. I subscribe to a hosted Exchange account, so iZimbra is something I would find very compelling and usable were I hooked to Zimbra account.
