Tor and privoxy had been ported to iphone and works very well.



Hi, there,
   I just ported libevent, tor-0.1.2.18 and privoxy to iphone 1.1.1 fw.
and finished a iPhone app named iTor.app.

There is almost no need to change the code.
just modify the project files(disable some configure tests and set
some default definitions) and a little code.(the default
MAXCONNECTIONS 15000 is too big, I use cygwin's value 3200).

these three definitions had been set to 1 by default:

USING_TWOS_COMPLEMENT
NULL_REP_IS_ZERO_BYTES
TIME_T_IS_SIGNED


It works pretty good on iphone. also I tested it with privoxy on PC
and tor on iphone.

for more infomation and source.

the patch is below, compile it with:

$autoconf
$./configure --host=arm-apple-darwin --enable-iphone
