Can I unlock my iPhone 4S using my Mac if my password (4 digit password) has been changed?

I left my iPhone 4S at my ex-girlfriend's house the day we broke up and so when i got home I put my phone on lost mode using iCloud on my mac. Got the phone back and she changed my password on the phone. Any solutions?

Take the phone to your authorized service provider and explain the problem, they should be able to reset it for you…
