I just got my iphone roughly 2 months ago and the phone bill is really killing me! I'm currently using the 3gs and one thing I'd like to check: how do we know whether the iphone is running on either E/3g? The E/3g signal at the top left is grey coloured when phone not in use and when I use the phone (e.g. sms and stuffs), it turns to blue. Does this means that the Edge or 3g is running?

Basically, does all applications in iphone is charged into our phone bill? Currently, I'm using the family plan. Would it be better if I convert it to the iData plan?

Please advice me as my bill monthly is around 400+! I would really consider selling the phone away!!

Then is it possible to track the internet usage of the iphone? Cause I would like to know roughly how much Ive used per month to apply the idata plan.

And also, disable cellular data doesn't help a thing. I've closed 3g function, and it uses gprs. Bill is a total nonsense! So how do I activate the idata plan? Calling 123 does anything??

Thanks psyeo. I've just called 123 to change the plan to idata. And i'll see how much is the phone bill by end of this month. thanks alot!
