If my phone is in my husband's name but I pay the bills, who is the technical owner?

Question Details: After fighting with my husband tonight, he took my cell phone and refuses to give it back as he is listed as the owner on the account. However, the number that I have had and used since before our marriage is the main number on the account. The automatic billing is also set up in the checking account that I've had since before we were married. Who is the legal owner of the phone? If I'm not the owner, do I have any rights to the financials that I've paid towards the bill?
