Spoofing the User Agent with Safari for cmwap

In Mac OS X terminal:
chao:~ mac$ defaults write com.apple.Safari CustomUserAgent "\"hicmwapiamcomingnow\""

Now your safari user-agent has been changed to "hicmwapiamcomingnow".
OK, go internet surfing with cmwap on Mac OS X!

P.S:
of course, you can go with gprsproxy tool without changing anything for safari.
