I follow the optional instruction here: http://www.droidforums.net/forum/dr...royo-step-step-installation-2.html#post528613 and install busybox. Everything went through without error. However, I don't know: 1. how can I tell if it is installed; 2. where is the | on the keyboard? I was going to compare the number files under /system/xbin to another phone (without the installation) but couldn't find | to complete the command, ie, ls -l | wc -l can someone help me? thanks!
