You can unlock your iPhone by resetting it and restoring the backup data from your ITunes account. Good luck with Android it's not like they even pretend to secure your private info. I would much rather have an Apple phone that at least takes security and personal info seriously.
It cannot get locked permanently, it cannot stop you from using it and it cannot interfere with your dive! You did read my first post?
So who is going to buy a device that displays another persons Name and Number and just accept an answer like "I forgot the password"? You would of course want a refund and if that was not forth coming you would contact PayPal, eBay or your credit card company. All of those entities would know the sellers real name and address. Also any sensible person would contact the real owner after they got their refund and let them know the case number with PayPal so that they can contact the police.
You keep maneuvering around the simple legal fact that as it stands right now if someone deletes your user info in a Teric it becomes theirs permanently, but If they cannot delete the information that DC becomes stolen property and will forever be stolen property that can lead to a possible arrest and a return of that property for as long as it exists.
Secondly someone is going to have to eventually send the unit in for a battery replacement and Shearwater would probably not return property that has a name and number discrepancy without contacting the number on the screen and verifying that everything is legit.
In a nutshell, a password system on just the user info makes keeping or selling someone else's Teric a lot less attractive than it is right now.
I’m in your camp. Would be a good feature.
