I have a Nokia 5185i slider version and my husband before he left placed a security code on it that locks up the whole phone! anyways, he has all of the sudden placed this security code of some type and I cannot figure out this code. I want to "get in". So for those of you who can appreciate my reasoninig for doing this please help! I believe it can be up to a 10 digit in order to do this and I have no idea what he could have used.
