Losing Contacts on a Phone is still Quite a Possibility

Given the four major ways to store contacts on a phone:

1) internal phone memory
2) SIM card/Micro-SIM
3) MicroSD Card
4) Cloud
     a) Phone manufacturer cloud
     b) if distributed device OS, then platform cloud (ie. Google cloud)
     c) Network cloud

&& possible different interpretations of the atomicity of a contact
1) email address stored in cloud (for user 1)
2) phone # store only in internal phone memory (for same user 1)
3) different views on contacts in cloud/device (ie. "All Contacts" vs "My Contacts")
4) different accounts in the same cloud

It's no wonder that contacts are still getting lost. :-}
