I believe the app itself (Gmail) is requesting to use Chrome.

So each individual app would need to request Chrome, something I'm sure Google's apps can do, but [insert random app here] won't.

Do you know if you can shut that off? I'm sick of being asked if I want to open a link in some other application.

Every time you update the app it'll start asking again. It's the worst part about using Google's iPhone apps IMO.

I don't personally know - but it would have to be a setting within the Gmail app itself AFAIK.
