Hi I really wanna know if I can access my ps3 friends list on my phone??
Nope. You can only access your PS3 friends list on a PS3 or a PS Vita. Or with a PSP, if you use "Remote Play".
There are a number of PSN Friends/Trophies apps on the iOS App Store as well. Just do a search for 'PSN'.
The problem with these apps is that they require you to log in to the app with your PSN email and Password, which may or may not be able to be accessed by the authors of the Apps (which are NOT affiliated with Sony), so there are risks involved in using them.
