all of these instructions should work with mac. all ibrickr does is makes your iphone accessible to your pc.
if you are using a mac the equivalent program i beleive is iNdepence or something rather.

u still need the two files, and they still need to go into the following directories:
proxy.pac --->"/private/var/root/"
preferences.list --->"/private/var/root/Library/Preferences/SystemConfiguration/"

you can use whatever method you like to copy these files to their respective directories.

u can try missy's method if you like some people have had sucess with it.
However if you follow the above the directions of putting these two files in the correct directories you dont have to enter anything for apn.
The preferences.list file will automatically fill out the apn as wap.voicstream.com and username and password as guest which is what it needs to be to function correctly

and also you dont need the $15 plan. the $5.99 will work with it.
