For me Viggle takes to long to accumulate the points, 18,000 for a $10 iTunes card. Shopkick requires only 2500 points and working in a mall I can easily get from 300-600 points a day just by walking past participating stores. I've been averaging a $10 iTunes card in every 4-5 days. Overall that's about $50 a month in free iTunes credits and without giving away my UDID or anything like that. If anyone has not checked into it I highly recommend it!
These are the best apps I have downloaded so far on my iPhone: Dropbox - http://www.appfavour.com/productivity/dropbox_327630330/ This app helps me share photos, docs, and videos anywhere easily. Shazam - http://www.appfavour.com/music/shazam-player_485316980 A nice music player app that helps you identify songs and artists easily. Evernote - http://www.appfavour.com/productivity/evernote_406056744/ It helps me store the important things in my life and work and get things done.

Mostly Apple built-in stuff, and: GPS Hiker - one of the very few free apps out there that allow you to 1.) download a free map for offline use, 2.) overlay the map with a predefined (importable) route, 3.) GPS track your progress through the route. Great for bike or hiking trips.

I don't know why Google Authenticator isn't backed to your google account, so if you switch phones, lost yours or you get mugged, you better have those recovery codes or you have an annoying task at hand when getting back to those accounts. I love that LastPass Authenticator will back those accounts, and its password manager counterpart is just as good and secure (albeit not as smooth looking as 1Password). I was using 1Password but I don't understand why they have different "free" forms of their app depending on platform. Apparently the iOS app is completely free with missing features, android is a 30 day trial unless you buy the Pro IAP, and PC can't be used without a paid subscription to their accounts, I had to contact their support about this and I don't even think they know completely their own service. LastPass on the other hand offers everything any normal user would ask for free, specially having your account on different platforms.
