New features with the new firmware

1. Fixes the reconnection problem with LG and Motorola phones.
2. Improved echo control for better audio quality.
3. Improved the DSP algorithm to fix the static/buzz experienced sometimes when streaming music from a BT stereo phone.

You must read the included Jabra BT620s.pdf file carefully before running the USB software update. The PDF contains useful information regarding the new firmware flashing and a slightest error will probably render your Jabra BT620s useless. So beware.

One thing I found funny about the BlueCore Device Firmware Upgrade Wizard, saturn-1-31-0.exe is that when check with Windows Explorer on the exe property, it says:

Internal CSR development version built on 23:Jun:04 - not for release

under the Special Build Description. Nothing major but I think you should know this before proceed with the USB software update.

Alternatively, you can try the Free Driver Scan.
