well, it needs to be jailbroken so you can A. either download the hack from the installer you get from jailbreaking it, or you will have to SSH iinto yur phone and add a .txt file that has the code written in it to unlcock the "server block" on the tzones plan.....your best bet would be to downgrade firmware to 1.1.4....thats what i used and the hack worked great.....except after awhile tmobile catches on to all the data being sent over their "tzones" network and they shut you off.....or they shuut me off anyway.....havent tried again sicnce but it was awesome while it was working......maps google you tube everything worked ANYWHERE. t mobile knows about this hack so idk if it will even still work....
