Phone Hacked... he asked me how my city is (he knows the name) and he knows my cable provider. Does anyone know how serious this is and if I should be worried?

I'm pretty sure your phone was not hacked.

Such information are easily to obtain by simply having your IP address. And by connecting to a link controlled by somebody you make your IP address visible to him. This means all the web sites in the world you connect to have this information about you, it is probably in the mails you write etc. You can try it yourself by visiting sites like whatsmyipaddress.com.

This means that these information by themselves are not really secret. But if the attacker finds out that you are surprised that he has this information then this knowledge can be used to mount social attacks against you, i.e. if you are gullible enough in this case you will be gullible in more cases. For example the attacker might "help you" to install a program which claims to better protect your privacy but in reality provides the attacker full access to your system or fills it with lots of advertisements.

Knowledge of your IP address might also be useful to mount attacks against your internet router because many of these routers are open to attacks and average users don't care about the security of these devices. This then can lead to really serious problems, like the one described in How millions of DSL modems were hacked in Brazil....
