My silent switch on my iPhone 3G requires A LOT of force to go back and forth and it feels like it's broken/jammed. Are all phone switches supposed to require this much force? When I tried my friends switch it went back and forth with ease and I thought maybe his was broken and mine was right, but now I'm thinking it's the opposite. Can I get this replaced and if so can ATT do it? The nearest Apple Store is 2 and a half hours away.
