Speaking of which, if you would like to keep track of data, another Cydia tweak.lol
WeeTrackData
It is a notification center widget.
Type in your monthly data plan (which is the same as mine).
And pull down notification center and it will tell you how much data you used in a day, compared to how much you can use without going over your limit.
Like you I have a 2GB data plan. So that is 1GB per 2 weeks.
So in the settings type in 1024 MB. That is 1GB.
This show that a person with a 2GB data plan can use no more the 34.1 MB of data per day to stay under there limit.
And it is extremely easy to stay under your limit when you know exactly how much data you are using at a time. Just sayin'.
I use to go over my data all the time before I got this tweak. It made me mad, because all you have to do is go 1 friggin MB over your 2GB limit and they charge you $10 for a whole GB.
So when I got this, Leaned how to use it...I have not been over my limit since.
