Hey, I think itunes is the only place to get them unless you jailbreak your iphone, which will allow you to install full apps without paying for them. Also, if you are after free apps, go to the app store and go for the top free apps. But there are tonnes and tonnes of great apps such as Ping, Skype, Fluther…HEAPS! Anything else just let me know. Note- I’m not encouraging jailbreaking the iphone
