PSP free wireless?

is it possible to use the psp with someone elses wireless internet, cuz it asks for some list of numbers having to do with your internet box or something. Are those really important? And does that mean you can only use your own?wondering cuz I'll be buying one soon and I cant seem to find the answer. :P

Wireless networks can be passworded and encrypted. Without the password you cannot use a passworded network.Whether or not you can use a wireless network depends on the network and it's level of security.It doesn't matter if you are using a PSP, DS, Laptop, or Desktop, it's all the same.

thanks alot, now I understand
