anyone having problems with theirs? when I plug in my phone it slows down and is almost unresponsive. if I plug the micro USB cable that came with my phone into this charger it thinks it is plugged into the computer. it says it is a 1A charger so I don't know what the problem is. I am definitely sending it back but wasn't sure if I should order another. I only paid 20 bucks for the charger, cable, and car charger through att but wondering if I should just order the blackberry chargers off Amazon for cheaper.
