Nah, it's a new SYS on the 6.5 side. Same programs installed. Are you using a lock pin too? Maybe try a different lock screen, and I'm assuming you don't have anything magnetic in your pocket? lol.
6.5 ROMs are up and ready for download, enjoy! There are Titanium and Manila versions available. No CHT, sorry, just install it by CAB. I also forgot the package for the Opera icon on the internet tab, sorry.... Anyways, they are on the FTP
HERE. Or go to the bottom of the second post.
