~im having the same problem right now. I noticed my bills been $40 a month more and called sprint , tech support said I downloaded from flycell. Dada mobile and have been charged monthley fees from them for 3 months! I never downloaded a thing from these sites! I looked at these sites and couldn't find anything that a blackberry could even support. They had me text stop to these companys and blocked them from accessing my account but only after theyed charged me roughly$120 dollars! I watch my account more closley now, duh, lesson learned. Hold ur ground and fight those charges. Good luck
