As people use smartphones more and more it is crucial that the smartphone keeps being safe. Important is to distinguish the ways security could be compromised. iOS jailbreaks for example, are bad for third party app developers and Apple since it enables users to download apps for free. However, in this chapter we will look for the security issues that are bad for the user, not for the companies.

To prevent app developers from abusing the possibilities of the Android and iOS platforms, both Google and Apple have implemented app permissions to ask if users

When there is no HttpOnly support none of your cookies will be safe and your account on the infected website might be taken over, which compromises your privacy. Long story short: a light browser version sometimes means more security vulnerabilities.
The use of 3G in smartphones also means more people are connected to the same radio tower. Compare this to a private WiFi network with a private router that only has to serve a few people. So this automatically means that if a tower is compromised it covers more customers who lose their privacy. And as this data is kept by companies like KPN you are in luck if you never live through such a hack. In the sources you can see a KPN tweet where they basically triumphantly say they store passwords in plain text opposed to hashing
