They are included in Android. The correct settings are determined by your SIM MCC and MNC (Mobile Country Code and Mobile Network Code). If you want, you can view the list of preset APNs by looking at the source code, for example at android-source-browsing.
The file name in this case is /etc/apns-full-conf.xml, but apparently it varies.

Next to the pre-configured settings from /etc/apns-full-conf.xml as described in onik's answer, some providers offer to send you so-called "service SMS" for an automated configuration. Opinions on those are quite confusing: Some say those do not work on Android or iOS devices, and you'd have to enter APN data manually (e.g. Simyo in Germany), while others ...

Yes, just copy the /system/etc/apns-conf.xml file.

I am having this problem too after inserting local SIM. Calls and texts are OK, I need to configure an APN for internet.
A Verizon Global Support Technician told me that it is beyond Verizon's control to add an APN and that Samsung will need to provide directions on how to do this. I got online to chat with Samsung and the guy told me he can't help me on ...

APNDroid doesn't work on CDMA phones. This appears to be the case with most such apps. Internet Scheduler and GreenPower claim to work on them if you have Gingerbread, though.
