OK, now you got me lost here, who are you addressing to tournique? I feel that a good address list is something that is really not complicated, it just sits there until we need it with no worries...
This is true. My windows phone can now sync with my FB and Email contacts as well. It is better to have multiple copies of your contact.. even sometime you forget who they are.
I believe that keeping phone contact is very important and one should always try to understand that they should always back up their data. Not backing up the data can sometimes make you lose very important information.
Yep, Apple devices to the same, they sync everything and it's something really useful, having all the devices standing with the same feet.
I believe keeping phone contacts is very important in ones life. I do think that living a good life also keeping in touch with people you know or would like to live with.
