asterisk users - Aug 2006 - GXP-2000 auf Betafirmware updaten?

Hi,

currently I use version 1.1.0.16 for my GXP-2000 which works really
fantastic. The only drawback I see is the addressbook.
Is the firmware 1.1.1.9 stable enough to use the phone in normal
environment? The webpage http://www.voip-info.org/wiki/view/GXP-2000
says that there it is possible to download the addressbook as a
XML-file.

The problem is if the version not works it is not possible to
downgrade to 1.1.0

Thx for any feedback,
Matthias
