Well I have tried searching and I just installed the 02 4.5 release last night on my new bb 8310 *just got it yesterday to replace a bad 8300*, however, I tried searching to get it up and running on my phone after I uninstalled the Vendor.xml file and I tried to do the trick to get BB Maps to show up on the 8310.. It says it is installed but I do not see it.. Anyone actually have 4.5.0.37 and have bb maps up and running successfully? How did you do it?
