There’s no way to get that password off without hard resetting or else it would defeat the purpose of a user set password. Would be kinda silly if anyone could access a phone without the lock password. Only thing you can do now is be a little more careful, anytime I change passwords I update a OneNote file I have with all my passwords and it syncs to SkyDrive. Also one of the nicest features of a windows phone is SkyDrive, you didn’t have the auto upload feature turned on? That is a hands down must. You will never lose a photo or video again. That’s what the feature is meant to do. There are beautiful apps that tell you every feature the phone provides which I always recommend reading. Even myself as a veteran have learned new things and even more I have learned what makes windows phones the best. Unless you figure out the password you set, your photos are gone. Please consider the auto upload feature as it only takes a screen tap.
