Gmail for cellphones
Gmail-mobile is a PHP application that will give you access to your account with any WAP-compatible phone (WML format), and you should be able to read your mail, compose message, reply, have access to your labels, etc (via Engadget)

Hey Chetan,
Have you heard of the BlackBerry?. Its does what g-mail does on a cellphone but at a much more larger scale.
I work for RIM where we designed and developed the BlackBerry. Check it out at http://www.rim.com
Take Care,

I’ve read some great reviews about the Blackberry and even read Nicholas Negroponte (of MIT Media Labs) commending the product in an article in NewScientist. Way to go, my friend (and I need your tips in buying the best model or are you guys cooking up something new that’s going to blow us away?)
