How to extract contacts from a manual backup-dump of my android phone?

[paulanathan]

I have an android phone - Samsung s2. After an accidental press, it went for version upgrade and worked for 2 days. Then it went on a boot loop for a day and stopped powering on and charging. When I gave it to recovery service company, they have taken a dump of the phone-memory and gave it to me in a pen-drive. Though, I can get back my photos, I am more interested in my contacts and sms. Can some one help me out in explaining the possibility and procedure to extract the contacts and sms from the dump I got in pen-drive..Thank you ..SPAN, Chennai
