I have a number of apps that I like but rarely use. I have been using Titanium Backup to uninstall the apps, but I do not delete the back from Tatanium. In this way, when I do want to use one of the uninstalled apps, I just do a recover via Titanium and I have my app back. This is very fast and I do not know of a downside to this. But that is my question, is there any downside to using this method to keep the phone much cleaner.
