I have previous hands on experience on integrating FB and G+ login in iPhone apps, working with RSS feeds, location information and localization. Personally I'm fluent in English as well as Japanese, so I had lot of opportunities to work with multi language supporting applications.
Briefing about me: I'm a well experienced software engineer and I'm an expert in iOS development. (You can verify my score in iPhone Development test, which is 95th percentile)
I can deliver the completed project in 15 days.
Your given description is pretty much clear, don't hesitate to contact me if you have any additional info or anything to be clarified.
As mentioned, I'm a well experienced iOS developer, but I was not actively taking projects from the freelancer website for last couple of years. This is a comeback, and I hope you'll be my first client this time. Looking forward to work with you.
