I know that because it was rooted before the gingerbread update I had to "flash," back to the previous version before the update and wipe the phone. I did that and then did the update to gingerbread and successfully rooted the phone. It took me about 4 days to figure out how to use my mac to do it and now nothing is seeming to work...I can't load my mac from a CD or usb drive. It doesn't show superuser anywhere on my phone (I wiped it by accident again while trying to load the liberty ROM). If someone can help me successfully root my phone on my mac I will be amazed.
