Ok, so I went to the apps for phones on the boost mobile website, and I wanted to download the instant messenger to my cell phone so I could use AIM. It said it was compatible with the i856 but when I send the download to my phone and download it, I cannot open the app. Instead it says "Authorization Error". I really would like to know if I could fix this or get a working AIM messenger for my phone. Can anyone please help me?
