Thanks for the advice, but as I've been saying, I need native instant messaging (like my "crippled" Nokia e62 and Treo 650 had, and my wife's RAZR has) because if you need always-on IM accessibility, a web app doesn't cut it. You could be logged out by their server, another web page could be launched by another app (e.g. email) replacing your IM web screen, and remember that the login and password are not stored. It's just unreliable. Native IM is a no-brainer for any free cell these days (or last year for that matter), and for Steve Jobs' "Breakthrough Internet Communications Device", it's shameful to be absent. I hope, and believe, Apple will get the message. Personally, I didn't complain about the price drop, because I felt I already received $200 of value in the time I owned it, but those who did complain made Apple take note. When iChat arrives, I will upgrade. But it won't come about while Apple's stance remains that Web apps are 100% sufficient... The change will come because of customers who challenged Apple to "Think Again".
BTW, funny you should mention Mundu. Here's what that page says: "[IMPORTANT] There are some compatibility issues with the new version of iPhone (v1.1.1) due to changes to the behaviour of the Safari Browser. These are getting fixed. Customers with the older iPhone (v1.0.2) can continue to enjoy mundu IM as before. " Seems like avoiding 1.1.1 remains the right call. Oh, and here's more from the Mundu iPhone FAQ:
How do I know when a buddy sends me an IM and I am not in the browser?
Currently we do not have an alert that comes up on a New message when you are not in the page.
When I navigate to a different page in the browser, will I be still logged into mundu IM?
Yes, you will be logged in and all your chats will be intact when you navigate away from the page. However, if you are away from the page for a long period of time, you may get logged out due to the limitation of the browser. We are working on automatic reconnect feature in future version.
