I rooted my Nexus S and re-installed a stock ROM. I had my contacts on my SIM card before starting to use my Nexus and I never bothered to sync those contacts to Google. After rooting I don't see my contacts anymore (even in the import contacts screen). However when I try to open the messaging app and type something in the "To" list, auto suggest starts suggesting some of the old contacts.
As part of rooting, I deleted all of my data.
How is it possible that message app is able to fetch my old contacts but I am not able to see them?
