With the current watches, you need to be connected to your iPhone for Siri to work. With the series 3 watches, Apple shows Siri working without an iPhone connection, but apparently connected to LTE. My question is will the non-LTE versions of the series 3 be able to use Siri if connected to wifi but without your iPhone nearby? Which makes me wonder if calls can also be made via wifi? On their website, in the watch comparison specs, it shows the Series 3 GPS version with a new W2 Apple wireless chip, so I was wondering if this is what that might be for and and other features it offers. I just couldn't justify the monthly service fee with the LTE Watch, so I've ordered the non-LTE version, and now I'm wondering what it will be able to do. Thanks.
