Was going to post the same thing. I use them as well. At their prices for cellular monitoring, it was a no brainer to pay for the service.

I had my system upgraded to 3.0 this week and the free IT-100 driver no longer has the same problem. Not sure if a new version is available for 2.X as well?
I as well as another user updated to the new IT-100 driver and were unable to disable partitions 2-8. Is anyone else having the same problem? It is annoying to have to select Partition 1 every time you go into the security system on the app.
