Facebook app won't work on my Iphone 3gs?

Facebook was being buggy so I deleted it thinking it would help and tried to reinstall it. It says it is not compatiable with my device and that I should update it. I went to update, and it said I was fulled updated. Is there any alternative app, or anything that I can do that will not mess up my phone?

Nope You Won't Be Able to Use it Because your Using a Older Iphone You Need To Have a Newer Iphone In Order To Install the Facebook App

You Can Still Use The Mobile Site Kinda Similar to the App m.facebook.com
