As you can see from this web page the newest firmware for ipLDK-300 is 3.8Ba.
However your hardware must be able to handle this new software (memory size).
From ver 2.2 to 3.8 you will get many new features, as I will describe in the next post.
To upgrade your ipLDK-300 it is adviceable to contact your local LG-Nortel representative, to let him do the upgrade.
The upgrade can fail, and the LG engineer is skilled in how to rescue a failed system.
See the next post for the new feaures.
