1- Connect to wifi or activate your phone, use your e-mail to bypass the pattern lock (this is the e-mail you had to enter or create when you first had the phone)

2- your contact are synchronize with your Gmail account, so you SHOULD have your contacts in your Gmail account, unless you disabled it which is strange.

3- to back up the user personal confidential information stored in your phone or someone else phone is not easy (in Android or Iphone)

Requires
- Root Access
- Phone MUST be in debug mode (no activated by default)
- Basic programing skills

Read the following article on the basic simple way of doing it.

you will not find many methods or way that will quickly do that, why? because it is really really strange to not be able to get your contacts with the following method unless the phone is not yours (and I'm not saying that the phone is not yours .... but many customers who come to me turn out to be that way)

1- Bypass the pattern by using your gmail account. (need WiFi or Active Service) it's cheaper to activate the service for a month and get the contacts.

2- Access your gmail and view or restore your contact.

3- Visit a metroPCS corporate store and most likely if you prove the phone is yours they will port the contacts & images.

It is hard in part to protect the privacy of your contacts, if it was that easy than anyone who gets his hand on an android phone will be able to pull the contacts of that persons phone (which is something really scarey)

and as I always tell my customer Always Turn your Debug Mode Off When you don't' use it. This way if you lose your phone it will be almost impossible for some one to access your files.
