Hello, I'm trying to find a compatible auxiliary + charging in one product for my iphone 4. - I know that some products give that airplane mode warning: honestly I don't care as long as it works. So what I'm looking at is the Kensington 2-in-1 charger (MSRP $39) and the Griffin Autopilot (MSRP @ apple store $49). Any personal experience with these products? Well...the kensington 2 in 1 is not available yet but only for pre-order. However, my brother has an older discontinued kensington aux+charger accessory that works amazing. It gives the airplane mode warning but the quality is amazing and I'm so sad to see it is no longer in production Which do you guys recommend? Or are there other products? Thanks.
