This update was taken down within 75min of it being up due to having issues bricking the 8350i. I work for TELUS and my dealer along with another one within my region is the only one doing a pilot project and have the software available to us through back end RIM services.
Jist of it is, that we upgrade clients phones as normal and if it bricks the phone we have to send log files to RIM, they are also providing us with swap units on hand just in case.
I have successfully upgraded 2 8350i's with the new software and it is a big improvement.
