People that give useless replies like that should be banned from every forum on the internet. Google answers is the worst - people just reply with "google it" even though it's obvious that anyone asking a question on there will already have tried googling it.
Profile name is whatever you want it to be, it's just so you can tell the different profiles apart if you have more than one (e.g. if you use the program with more than one phone). APN is the Access Point Name - I think that can be set to whatever you want in the phone's settings. I know the default for KS360s on the Orange network is orangeinternet, but I'm having problems getting my friend's PC to connect to her KS360 so I could be completely wrong about what's supposed to go in APN :)
