Got a new phone and updated to 2.3.20 OTA right away. I'm kicking around rooting the phone and installing the Star Wars zip. Can I safely install it on a 2.3.20 phone? If I have a problem I can only use a 2.3.20 sbf to recover correct? Searching isn't quite yielding detailed enough results for me to feel comfortable attacking this. Any information about what I have to be concerned about when rooting a 2.3.20 phone?
