Here is a great guide I was introduced to via twitter. If you follow all the instructions you will successfully root your android phone.
To reboot RA = Restart Phone and Hold down home button until recovery menu is brought up
Download and add this recovery image instead of the one provided in the guide, works faster! pretty much replace the 5 with a 6 (read the guide and you will see what I mean)
Here is the guide! FOLLOW ALL INSTRUCTIONS NO IFS, ANDS, OR BUTS!
