Is there a program I can download to back up my contacts?

[killeronly001]

I used to have the HTC Diamond Touch, I had Microsoft My phone installed in my phone. Whenever I touched it, it would back up all of the information including my contacts, calender, text messages, and my pictures into my account.

I just got the HTC Evo, and I can't download Microsoft My phone, I can't transfer my contacts on there into my new phone, I have to put them manually. I am just wondering isn't there anyway I can back up my contacts to an e-mail account or somewhere without having to connect my phone to the computer? I want something like Yahoo To Go, where I can just hit one button on my phone, and I sync all of my information.

Thanks in advance.
