Whoa!! i thought i missed something here with all the activity for today. And no theres no MMS on these phone with the upgrade for us sprint 8330 users. Also, this still isnt an official upgrade, i just went to blackberry.com to see if it was available for us sprint users, and it still says that 4.3 is the latest OS. 4.5.131 is very good, but not official yet though.
