Every night I usually charge my phone via USB cable tethered to a computer, but tonight I decided to hook the phone up to an A/C adapter instead, to see if the phone charges faster when plugged to a wall. While the phone seemingly charged faster, while removing the phone from the plug, I noticed a light leak coming out of the SIM eject hole. Is this common? I'm guessing since my iPhone usually charges next a brightly lit computer when connected to USB, I wouldn't notice the light leak, until I took the phone to a fairly unlit area of the room. It doesn't bother me enough to want to seek a replacement, but is that a common issue for other users too?
