The network usage is correct. Total bytes received 57 KB and sent 36,74 KB, yesterday, that's when I reinstalled yappari again. Yappari works fine, but also, yesterday my phone download again 5119 Kb two times, automatically. My repositories are disabled. I didn't use internet yesterday. I don't know where is the problem. Curiosly 5119 is the same size yappari application and this problem, curiosly also, I have it from the day that I updated yappari application to 1.0.37. I will continue controlling. Next thursday I'll phone to vodafone to explain to me where my phone connects. Now, it isn't possible that they are in billing period and they can't provide me, today, this information.
