Welcome back. I'll share my friend's horror story as a welcome mat:
She has a Samsung S4.
It's had its hiccups and glitches but she's adamant that she does not like Apple.
She uses her phone for work, she works in an advertising agency.
Her phone apparently got a software update overnight that she hadn't even agreed to.
(The same thing happened to me with my Note 3)
She called me in a panic this morning, because:
ALL her contacts are gone. Every single one of them.
ALL her calendar entries are gone, and when she called a coworker to try and get at least some of them back, her phone insists on putting everything in GMT, which does her no good.
Her client specific email folders are gone too.
She contacted Samsung and they were no help.
Soooo... WELCOME BACK, WE HAVE ICLOUD!!! ������
