Sorry for my ignorance...new to iPhone..what's cydia?
Oh ok. Well u ve got a lot to learn then. Some apps are not accepted by the official Apple App Store therefore they release it on cydia. Which is an app that u will get only after jailbreaking your iphone. Depending on your device model and firmware, this may or may not be done. I will not detail here the advantages of jailbreaking but google it and u will find PLENTY of information. Go to the tutoirials section of wwww.iclarified.com to see if your device is jailbreakable
