Ok so I did jailbreak my iPhone and have started to view the apps. I have noticed that a lot of apps are paid apps. I went to log into Cydia and they wanted my google or facebook info. Then to buy apps I need to give my paypal credentials. There is no way that I know to purchase outside of my iPhone. I am concerned of apps that might be rogue and steal in info and then there goes everything. Should I be concerned or am I over reacting?
