Sure, let me know what you'd like to see in there. If it shows Unknown it's because your friend either hasn't populated that field in FB, or they've got them hidden in their privacy settings.
1. I checked into that, and checked the website version of Facebook. The "Relationships" and "Birthdays", sometimes "Hometown" all show up as Unknown on Frienatic, but aren't hidden or unpopulated on Facebook.com.
2. Also, it be nice to see "Mutual Friends" when going into a person's profile. Maybe adding a button, right next to their info would help.
3. Haven't seen this mentioned yet, PHOTOS ALBUMS!! The only place I seem to access photos is when I click on a person's status, and their "Recent Photos" show up, if any. Definitely Photos/Photo Albums is a much needed request. Maybe adding a strip at the bottom where you can swipe through different albums, could do the trick. Once you open up a album, you can have a grid of all photos, and click on each one to see in full screen individually, or swipe from there, left n right.
4. As far as what info should be shown on the profile, the following could be a start:
Education and Work (College + High School)
Arts and Entertainment (Movies + Music + Television)
Contact Information (Phone #/E-Mail)---> Hint: Maybe have the option to add contact info to Calendar, or open up e-mail link with the "Mail" app.
5. Another thing I came across is using the Search option in "Friends", sometimes when I would type for instance "Jay", it would take me to the friend's grid/page BEFORE the actual grid/page where the person is actually on. Not sure if that makes sense.
6. Messages/Events/Notifications (Not Push) Sections?
Sorry if everything sounds overwhelming, but I figured I jot them down before I forget. I'm sure its gonna take a couple revisions and versions to get to where the app is nearly perfect. Also believe not alot of these things can be made possible due to their API's. Made alot of progress for an app thats only been out for nearly a week.
