Delete ALL service books from your device except for BlackBerry Maps and BlackBerry Internet Browsing Service. Then do a battery pull. When the device reboots, resend service books from BIS site. Then your media player and browser will both work assuming you followed the steps properly. It's a pain but it works.
NOTE: when you delete the service book Provisioning it will still show but no worries.
i think is BC internet browsing service (browser config)
Here it is highlighted in blue
I got my media player working again but still no browser. And now my Navigator is gone. the Blackberry Internet Browser is service book isdef not there. Here's the screenshots of my all of my service books
There was one service book not pictured because it is at the bottom and i didn't wanna take a screenshot for one service book. its called: Wi-Fi TCP/IP Transport [WPTCP]
I'm on 3g
Have you tried calling your carrier to see if them resending your service books helps?
Yahoo Messanger™ doesn't work on my device :(
I love having the feature to either choose 3G or EDGE :)
