Having the device and version info slaved to a particular symptom complaint is always a good thing! But I'm nor sure if the profile is the right place, because it shows your latest profile even if you post was written a while back. Many of us are on device #2 (or more) since starting playing DF, and players like Hel have multiple devices. When we change our profile (e.g., my Android jusy updated from 4.1.1 to 4.1.2), now the old post that described symptoma under 4.1.1 is misleading.
For now, always state device and os version, and DF version, when citing symptoms.
Good idea though!
