This firmware fixes the Custom POI categories problem on my 2595!
Many problems with the SmartPhone Link apps (Dynamic Parking, My Garmin, Weather)seem to be fixed. Saved and Recent items now sync properly from the 2595 to the phone.
There is also an updated Garmin Smartphone Link app (1.3.1, July 18) in the Google Play Store. My preliminary testing was done with the 1.2 version of the app and a Samsung Nexus S phone running ICS.
