The SmartaFone installation takes only minutes to install on your Exchange Server. Once the instllation is complete you will have the SmartaFone Task Manager application available, which is all you need to set up multiple users with multiple Public Folders.
There is nothing to install on your Smartphone, no matter which make or model you have.
The image below shows the Task Manager interface, which is simple to use and has a wizard for creating new Tasks. Each Task synchronises a Public Folder to a user's Private Folder.
Tasks can be viewed either by user or by Public Folder. The number of users you can add depends on the licence you purchased, however, any number of Tasks can be created, so you could have many Public Folders on a single Smartphone, having purchased a one user licence.
