OpenAppMKT is the best iTunes alternative. It has many apps, tweaks, themes and specially games for iOS 7.1.x, 6.1.x and all older firmwares. Cydia installer is also available on their app store to download for free.
OpenAppMKT users, the developers of Cydia installer who have developed the package for OpenAppMkt website, are claiming that it actually works even without jailbreak. There are thousands upon thousands users who are downloading package from www.openappmkt.com
So, we also tried on of them on our iPhone 5S and iPad Air with iOS 7.0.4 and iOS 7.1 without jailbreak them. The result was, the packages are just fake. We had downloaded the installation packages for iOS 7.1 and 7.0.4 and both packages were not working on iPhone 5S and iPad Air.
We are not saying that OpenAppMkt is fake or scam, but we are sure about those packages. We hope that the owner of OpenAppMKT will remove those fake packages from their site.
Update: The OpenAkk MKT site is not working. It seems like the site is down or they have step down and went offline. However, there is a blog from official website and that can be accessible. If you wanna ask anything, you can comment on their official blog. Open App Mkt support team is very supportive.
