well, I did enjoy hacking mine for two weeks. but when I install a lot of different software, something is damaged inside. download is not working. this kind of sh** happens few times. I restore it for three times. well, it's interested in using games or various apps. but in the end, it causes ipod touch some malfunction. so I return to orginal setting, and totally erase ziphone crap. I just wait for firmware 2.0 update with itunes 7.7. it will be much better than hacking.
