Iphone screen broke, need info on it

Dropped my iphone by accident at work and the lcd broke so I can't see anything. But everything works fine. So I'm using my backup blackberry phone but there are numbers in my iphone contact list that i need and I never really backed up my iphone before hand because its an old 3G and jailbroken. I just need to know how to get the contact list from my iphone to my computer some how… Thanks!

The screen not working doesn't affect the rest of the phone at all. You have several options:
-Plug it into iTunes and make a backup. Then restore that backup to a working iPhone, iPad, or iPod Touch.
-Connect your iPhone to iTunes. Click on your phone on the left side of your screen. Click the Info tab at the top. Check the "Sync Contacts" box and select Google. Sign in to your gmail account and sync. All of your iPhone contacts will be merged with your Google contacts. You can then see all of your contacts at www.google.com/contacts. There are other sync options in iTunes, but I do not have experience with them, so I can't recommend them to you. The only one I know will work for sure and will merge your contacts, not replace the ones on your iPhone, is Google.
-Get your phone repaired. I repair cell phones, and I do it much cheaper than most people you are likely to find. Here is a link to my Craigslist ad pertaining to the iPhone 3G:

I charge $30 to repair a phone in a condition such as yours. If you are interested, you can find my contact information in my ad. You can also feel free to contact me if you need further help with the transferring of your contacts.
