Well I got tricky. I got the new "update" notification for 1.4.5 just as I was preparing my Sprint FrankenPre2 surgery. So I blew it off.
I knew I'd have an extra update to do after my metaDr to get the voice dial working, so:
After my metaDr I didn't do the update yet. Got apps redownloaded and Maps asked for restart so I did.
Then I went to check for updates and there was one there with different text than before the Maps update. I accepted.
Restarted and everything looks squeaky clean, voice dial, maps and all! (And holy cow does the GPS lock faster on this Pre 2!)
