Just to be clear, I'm not ragging on you or your comment at all, because I see this all over the place and it's not something specific to you.
But it's interesting that a lot of people might credit iOS for adding this feature, when my (Android 2.2/2.3) MyTouch 4g had this functionality almost 10 years ago.
What a strange comment. GP wasn't claiming that iOS was the first to add this feature, and besides, does it really matter who added it first? They were just helpfully pointing out its existence for anyone who may not be aware.
The only reason I brought it up is because they called out iOS as "just adding it" when Android has had it for years, even though the original post said nothing about iphones.
Seems a rather cryptic way to go about things with your health on the line.
