I recently got a green dot usb ac wall charger. It works but the problem is I can't really use my ipod when it's plugged in that way. When the ipod touch is plugged into usb on my computer I can still use it while it charges just fine. When the ipod touch is plugged into green dot apple usb wall charger it charges but it's kinda hard to explain it's like the touch screen isn't working right. I can touch an app but it does nothing or I have to tap the app 5 or 6 times for it to open, or I'll touch the app but another app will open instead. It charges ok with no problem. But I've rebooted it, done everything I could think of. It works fine plugged into usb on computer I can run apps while it's plugged in. But plugged into wall charger it just acts weird as in the above mentioned symptoms. Soon as I unplug it from the wall charger it's back to normal no problems. Any ideas? it's one of those green dot apple wall chargers got it on ebay and it's not a knockoff. I dunno just sucks I can't use it right while plugged into wall cause the wall outlet is next to my bed -grin- and since 3d wifi games only last me about 1 hour and 40 mins on a brand new ipod touch 3rd gen I would like to plug it in instead of worrying about the battery.
