Yup!  10.3 is a very good update.  I was able to pick up some Android apps I've been wanting from the Amazon App store.  They run great...no problems.  As long as the files are made available on CrackBerry, I can update my Z10 anytime I want.  Actually, I prefer it that way.  No more waiting for the carrier to release it.  Still a shame that some of the newer BB phones aren't carried by Verizon.  Perhaps one day CDMA will no longer be an obstacle.
