Thanks for this. I have a quick question for one of you experts. My S4 shows up Tuesday. So tomorrow I’ll back my phone up again (do it once a month) into iTunes. So when getting my new watch, just turn the old one off, connect new watch to phone and it should ask me to use previous backup of some sorts and installl anything/everything? If that is correct I was planning on turning off Bluetooth after th new watch is done, turn off Bluetooth on phone, then find a setting in the S2 watch to factory default so I can send it in for the exchange?
