no

the 250mb is ONLY when running 2g/3g connection, NOT wifi

As an examble last month i had wifi on for all my permanent stuff at home

all 3g updates for twitter etc used about 200mb

 

I would suggest you keep wifi on at all times when it is available, otherwise any apps connecting to the internet will use your data

 

Personally i use - 3G WATCHDOG

+1 but I don't use it as I have a 3GB data plan, and I've only ever gone over it once in nearly 2 years, which was when I didn't have broadband at home, so I was using tether apps

 

hahaha so do i but its neice to see how and where i use data when not connected to wifi

simply cos i can

 

Why bother with Timescape at all if you only use it for facebook? I don't see the point. Just use Facebook for Android (download it from the market even if you already have it -- I found the one my X10 came with was actually out of date even though the version number appeared to be up to date. I re-downloaded it and got better features).

I use a data counter called... Data Counter It works just fine, it monitors both my 3g usage and my wifi usage (even though I don't really need it to monitor my wifi usage, but it's nice to be able to see what I -would- have used had I used 3g) and puts them in separate categories, and then counts everything by day / week / month / total.

Since installing the app maybe three weeks ago, I've only used something like 180 megs, and I did a lot of surfing PLUS I tethered it one day to my netbook and surfed the net that way for a couple of hours .. I'm kinda disappointed in myself, because I have a 6 gig dataplan, obviously I have to kick my data consumption up a bit rofl. Time to do more tethering.

That being said, every time I put my phone away, I turn off 3g, so I don't have anything polling the 3g network / pulling data while I'm not looking.

 

I use Call Meter NG. It's free and monitors the usage of calls, SMS and Data with lots of different features to suit your billing mode. It works a treat.
