I used to use Friendly facebook for iPad and they have changed it so much that I really don't use it anymore but they're telling me to update my iOS to 4.3 for Friendly to work. When I go to see if there's any iOS updates when I go inti iTunes and have my iPad connected, it says there aren't any iOS updates. I'm running iOS 4.2 right now with 14.GB available total. My nephew got this iPad from the college he goes to but didn't want it so he gave it to us. I am currently using mypad for facebook but am looking for something better to use that's free for facebook that also let's you do chat.
