Two things I've noticed with 5059:
1) The "contacts" softkey within the phone app doesn't display "Contacts" properly but it functions just fine (pressing the screen as well as the softkey calls up the contacts app)
2) No "smart" dialing
That is, trying to spell out the name of a contact in the dialer does not produce a list of the possible matches...does that make sense?
Just a heads up, this build is, as the trend clearly shows, the best yet!
