how to change password to unlock iphone backup

I have tried all my old passwords and the ones suggested here '0000', '1234', etc., tried the Elcom password finder which came up with 'No password found' on the backup file which makes sense since there was never one set but this doesn't help as I am still having no luck and still am asked for a password for the backup. I went to the Summary page on itunes as suggested above and this showed no password was set so I set one (First time and now if I want to change it I have to put in the original, hence no password was set previously) and then tried again but still no luck. Emails and contacts are ok as I have restored from google. Similarly I had a lot of important texts and photos that I need to get back. I also did not have a password set for my backups and it still asks me for one. I know there are a lot of answers here and I have tried them all with no luck. I still can back up the phone and well, I wish now it wasn't encrypted now, Oh well, any answers would be appreciated. I think apple dropped the ball here on this one. So I guess unless I reset my phone the back up is encrypted forever, although I dont understand that since I was the one who created the password to encrypt it. I tried to un-check the encrypt box for my phone and it ask for the password, no biggie right? I mean I just created it so as to protect and encrypt my back up, I go to decrypt it and I cannot do it. I then went back to decrypt the files and now the password does not work.

I backed up my iphone 3gs and checked the back up files, in at least the ones that were ledgable and they no longer were ledgable, they were all encrypted.

So, I checked the box to encrypt back up files and it ask for a password, that's when I created a password. Well, my phone originally always worked with me while backing up, still does, my dilemma is, I decided to see what this encryption thing would do.
