Basic Installation - allow 5 to 10 minutes.
This 'starter' installation will get you going quickly.
For enhanced functionality, please check 'Complete installation'.
You can also perform these additional installations later on by choosing 'Add/Rebuild' and selecting the desired items.
The basic installation adds:

- assorted tools, scripts and daemons (prefixed with _bSE_)
  which will allow iFuntastic (and you) to run code on the device
- a bSE folder in /private/var/mobile/Media/ to hold most other iFuntastic support files
  and placeholder web clips to allow gaps between applications on the Home Screen

It will also create a File and Folder index and make an application list.
To the best of my knowledge these additions will not interfere with existing installations and features. Please let me know if you do have any problems.
