Update to the remaining mobile instances
We have updated some of the mobile instances to the new version. The remaining mobile browsers will be updated shortly.
Different resolution
Be aware that the default resolution for the new mobile versions might be different than the existing resolution. For example, the iPhone5 will be 320px by 580px with a default scale of 2 (instead of the current 640px by 1136px). You can still get the scale used for the screenshot as part of the API call screenshot/info.
