I have been keeping an eye on updates to Slacker Radio for BlackBerry 10 hoping for offline caching but sadly it has yet to come. Still they just pushed out a new update today that brings some improvements all around. Specifically they have called out the following changes that this build addresses:
- Improved handling of network disruptions
- UI Fixes
- Battery use optimizations
Check out the latest version here in BlackBerry World and make sure to bug them to add offline caching!
