I purchased my phone December 26. After much deliberation and hours of reading, I rooted on February 14. I was nervous and apprehensive but thanks to Matt guide and his assistance, I made the switch to "Rooted" without a problem. Last Sunday, I moved form BB7.5, a 2.0.1 rom to BB v0.4 which is a 2.1. It really was not difficult. Prior to the wipe and install I read the Nandroid instructions several times. Now that Matt has rewritten his process you can do anything with these phones.
