I am looking for a good 2nd Gen ipod touch case to use while running. Things that are important to me: -protection if dropped -relatively waterproof from sweat -access to volume buttons -easy to navigate while on my arm I am wary to buy one because I bought one (DLO flip non running) at best buy that was clearly labeled "2nd Generation" but it was EXACTLY the same as for my 1st Gen touch, ie volume buttons are covered up and inaccessible. (I returned it after I opened it in the car, 3 minutes after I bought it). Any suggestions? Thank you!
