I've got a good idea for an application that I can make.
It's basically a PHP script that I'll put on a webserver, and it'll check my email & MMS my cellphone any emails that I receive.
I know that there are a lot of similar products such as BlackBerry, but you have to pay a subscription for that. There are also cellphones that allow you to check your email via POP3, but that requires you to check for new emails, rather than have them sent to you automatically.
Another (main) reason why I want to do this project is that once I've completed it, I'll be able to incorporate SMS & MMS sending into my web applications, so I could make my website SMS users certain information.
As soon as I have some spare time I'll start work on this...
