allen2oo3, the link provided by CSO takes you to a PIBB forum page with yet another link in the 1st post. I cut and pasted the link for your benefit:
Index of /FTF/PIBB/Beta
As seen, the above link takes you to the page where you can download the latest PIBB build. Remember to add your registration (if not coming up automatically upon startup, go to Menu key > Options> About) or PIBB will work in Trial Mode (full functionality, limited data in).
I hope this helps.
PS A suggestion: Register 1st, then sync your data in. (If installing over an older, registered build, you may not have to register again. New builds always resync regardless of registration.)
