AFAIK it's just a concept, no files have been released. Plus, they're infringing on PimlicoSoftware's trademark with the name. Seems to be a few somewhat clueless programmers who hope to make something, but haven't yet. Maybe they'll get something out, but they need to change the name first.
AFAICS, there is "files" for Bora, but for Chinook released only Contacts. So I can't to test this program, because I have an N810.
OTOH, I just checked the 'Contacts' - this is very simple application (simpler than a standard one) and this application isn't "hildonized" - menu is just an separate and always visible bar under application header.
So let's wait. Maybe later this product will more usable, but not now (for me, at least)
I found the Pimlico Contacts program to be very well integrated with the built-in contacts.
The only real problem I have with it is that their file browser sucks - it can't access "hidden" directories and files (where the name starts with a "."), which makes it pretty much useless for accessing the standard "images" path for adding a picture to a contact, for example.
I wanted dates, so I went to the date page, it sent me to a home page. The home page had a one-click install, that failed with "conflicts with installed software" but no details as to what conflicted on the screen or in the application manager log.
So I tried adding the repository using the directions on the link provided, but that failed with
"E:Malformed line 29 in source list /etc/apt/sources.list (dist parse)"
The only difference I could see in that line compared to others was a components item (which the distro instructions left blank, so I did) and I added "user" to it in app manager.
and indeed, http://maemo.o-hand.com/packages/dists doesn't exist. So whatever the app manager is using to determine that path is wrong or else the repo is wrongly set up. Either way, not usable.
