rooSwitch Lite

rooSwitch Lite exists to make it easy for you to create different profiles for each of the applications allowed in the Lite version.

You then switch amongst the profiles to activate the data you wish to use. It's like a multi-user environment for just one application.
rooSwitch Lite is rooSwitch's free, little brother. There are a handful of things this little guy can't do, but plenty that it can. The biggest limitation is that this free version limits the switching to a set of pre-defined applications.
rooSwitch Lite is limited to switching the following applications:
Address Book
iTunes
iPhoto
Mail
Safari
Stickies
