it seems to work about 50% of the time. let me explain. I plug it in the wall, then to the phone and the icon doesn't say it's charging and the battery continues to drain. I try a couple different plugs and finally one works. I hear a bling sound and I have power. then I try the original plug again and it works this time. I didn't know if maybe I was plugging it in in the wrong order, so I've tried: first the wall adapter then the usb then phone. then I've tried usb-adapter-phone-then wall. it doesn't seem to make any sense. I've also had this problem at school and at home, so I don' think it's my outlets especially since the couple times it didn't start charging, I tried the laptop, and it worked fine. I've also tried unplugging and re-plugging a bunch of times, but that doesn't seem to do anything. it's like once it decides it doesn't like the outlet, it won't work. This is a US plug btw. I hope it's nothing really dumb, cause then I'll feel stupid but I've tried tons of different things. Also it works every time in my mac pro without the adapter. (which might be the culprit) Thanks guys. I tried searching for this problem, but just came up with a bunch of old 3g prong breakage problems.
