  • Turtle Beach M3's: Good for Pc gaming? Like the title says. I used these for Order and Chaos in my iPhone, but the package say you can use these on pc as well… Now, when i tried to use these on Planetside 2, everyone said the couldn't really hear me… Is there special software I should install for this?
  • Is this a good trade: my gaming PC for an iphone 3g? My gaming PC had an i7 processor, GTX 770 GPU, 120 GB SSD, 2 TB HDD, and Windows 8.1 OS and I traded it to my friend for an iPhone 3g 8 gig version. Is this a good trade? Both the PC and the phone was used.
  • Is the Iphone 5s good for gaming? What I'm really asking is I would love to play really good yet big games such as free roam games and MOBAs which tend to have a lot of lag and crashes, will these kinds of games crash on an iphone 5s?
  • IPhone doesn't give me option to setup voicemail? So I have voicemail messages pending. Whenever I press the voicemail icon in the phone icon, it just starts to call the voicemail but it just gets disconnected. I have never set it up & it's not an option in the phone settings either.
