I am just curious, does anyone know how much data can be used just sporadically checking your facebook account on your phone? The reason I'm asking is because when I ordered my droid incredible phone, I just went with the $15 150MB data plan. I really won't be using the phone much for checking mail unless I absolutely need to, and etc. I'm usually home a lot anyways, and have a PC that I can get on to check my mail and what not. So I was just basically curious if I were to jump on my phone to kind of scan through my facebook and that's about it, how much per-say it would use of the data plan.. I hope what I am asking makes sense?
