Sorry, the features are not available for purchase.
Firmware and Device as iFuntastic sees it, is
Firmware Version
Please make sure this version of iFuntastic supports your device and firmware:
The minimum supported version of firmware is , and the maximum supported version is .
Apple do not support jailbreaking (and iFuntastic) in any way, and therefore very liberally change things around from firmware to firmware. Usually this requires modifications to iFuntastic and a new release.
If your version of the firmware is older, then previous versions of iFuntastic may support it.
If it is a newer version, then please be patient until I have caught up and released a new version.
Either way, please check on iFuntastic.com.
Communication Problems
Depending on the configuration of your computer - model, OS X version, iTunes version - iFuntastic may have problems communicating with the phone. If the firmware is supported by iFuntastic but is not identified properly, then you should try the following options until iFuntastic can identify your device:

- push the status button to update the status; do that after each step that may have fixed communication
- unplug your device, then plug it back in
- plug it into another USB port
- quit and restart iTunes
- quit iFuntastic and delete its preferences file: ~/Library/Preferences/com.bSE.iFuntastic.plist
- restart the device (switch it off, then switch it back on)
- quit and restart iFuntastic
- restart your computer
- reinstall iTunes; instructions from Apple can be found here

Try some of these at least. You can also send a bug report which may shed some light on the problem.
Otherwise, please try a future version of iFuntastic.
