I used to have an Android device, and let the thing sync my Facebook contacts into my phone. What I wound up with was a mix of people I'm actually friends with, and also a big collection on "Facebook friends" ... those people I'll never ever call, but knew from back-in-the-day and wanted to connect with on Facebook. I don't need them in my phone today because the extend of my correspondence with them will be what I consider "two-way read-only". They can look at my FB stuff. I can look at their FB stuff, but that's pretty much the extent of our relationship.
I'm on an iPhone now, and know that iOS6 will give users the same option ... to link your device w/ Facebook ... sucking in all your "FB friends". I won't be enabling that feature, and while the software apparently indicates you can disable this part of the connectivity, I'm reluctant to even link it for fear that it'll immediately hose my contacts in a way that requires me to manually clean out that kid I went to middle-school with many years ago.
