Help, iPad passcode wrong?

So I just changed my simple passcode to a passcode with letters, and I decided I didn't like it so I tried changing it back but when I try to enter the passcode I just made it's telling me that it's the wrong passcode

How would I go about fixing this? I'm using my iPad right now and I can't lock it otherwise I'll get locked out

Only problem with that is I currently don't have a computer that it is synced to. My old windows laptop crashed and I've been running my iPad solo for a few months now :/

It may sound that way, but it isn't. I've got the box and everything. Had it since march.

It's currently in the never lock the screen mode, so it's on. I'm trying to salvage my data using iPhone explorer, but having no luck on the passcode yet
