A tip for #Android users with rooted phones: get Titanium Backup and use it to back up any app before you update it. Then, when a new version of an app sucks, you can roll back to your backup version. I've lost count of how many times this has saved me when an app developer breaks something or adds an "improvement" that is no good. I've even used it to help my IT customers a few times when they needed an older, working version of an app because the current version in the Android marketplace was broken (*cough*MicrosoftOutlook*cough*).

I think it only works on phones with root access, though, so it's not for everyone.
