Got an SMS from a new contact I know, saying simply "hi it's Jane and peter"
I don't have any address book entry existing for this person but the phone suggested "maybe:Jane" - ok, I can see that conclusion
However, tapping the banner at the top of the message it said "contact info for Jane.. blah blah cellphone number 123 456 789.. found in Mail"
And then it showed a mail from my account manager at my insurance broker confirming a policy detail - entirely unrelated to this person, the trailing phone number digits are different, all names are different, they'll never have met or interacted etc. I can't find anything they have in common - just wondered if it's reliable, how it matches, what data big brother is linking up to offer this assist etc?
