Hello, everyone. Unfortunately, ear speaker grill gets dirty quite often for me. Certainly, there are many ways to clean it. So I used a small soft brush to get the job done few times. But recently I discovered that grill becomes kinda deformed a bit in different places. I can see it under bright light under different angles. It looks quite imperfect comparing to out-of-the-box condition when it was white and shiny. It's strange that metal is that soft. So I wanted to ask iPhone 4/4S users, who use their phones for like half of year, is your grill still looks perfect and does it get messed up with time or cleaning?
