Bare with me while I get to my question.

I have Apple MobileMe and I like it a lot. I've been using it for almost a year now. I know the web mail interface can be slow at times ☹️

I use my iPod Touch with MobileMe and it's great how the email, contacts and calendar apps on the Touch work with MobileMe.

I'm already an at&t customer, and my plan was to get the iPhone for the same features, but I'm wondering if I could access MobileMe features using a different smartphone. I'm guessing I could use IMAP for the email, but what about the contacts and calendar?

Any ideas from any of you?
