Depends on what friends you got. ^^ In the situation where 11 out of 12 is owning iPhones, it's always those who owned an iPhone 3/GS feeling embarrassed to put their phone on the table, and eventually hide them underneth. The rest of the, say, 7 iPhone 4 owners are not that proud afterall, as it'd like the awkward situation where you find you and others dressing alike in a party. The could compare their unique taste with cases, but that conversation would die pretty fast. The 12th odd phone taken out can always attract the attention and question in this situation. I've never ever running into a group that take proud on having taken the majority choice on phone.
