I think VZW may have released .77. If you are still having issues and you think .89 will help you do the upgrade. Remember, upgrading your OS to something other than your carrier will in most cases void your warranty. Follow all published guidelines for an OS upgrade, especially the backup procedure. There is also .97 out there (do a search for it here or on google), it is a stable OS used by many, including myself. I've had it for over a month now with no issues. However, just because it works ok in my phone doesn't mean it will do the same in yours. Caveat Emptor. Buyer Beware!
