6 Aug 2009 - v1.1.3 - Update
It's been a while, but this minor update has the following changes:
- Fixes a bug with the "switch off after Bluetooth" call function.
- Fixes a bug which caused the left soft key to be pressed at the end of a call.
- The "switch off for Bluetooth", and "switch off after Bluetooth" facilities (which switch the screen off during, and after a bluetooth headset based call respectively) are now applicable to wired headset calls too.
