HELP! My iPhone is leaking!

Question

leaking money.
I have my phone set up through gophone Pick Your Plan without the edge data package.
Every 10 minutes or so I get a message that says "Your last transaction cost $0.01." Anyone know why I'm getting this message? I find it weird because my iPhone is connected to my home wireless network, could it be something besides EDGE that's causing this?
This is a recent problem(started happening yesterday). I've had my phone set up without data for 2 months now without any problems like this.
Thanks for any input or help.

I have one of my iPhones setup on the Pick a Plan as well. A few tips:
Close any widgets such as such as weather and stocks. They use edge and you will be charged money for these. They continue to update every few minutes eating up your money. If you leave weather open and press the sleep button, it is still active and will use edge to update every few minutes. Even if you have WiFi enabled, it switches to edge while on sleep.
As pointed out, email uses edge also while on sleep, even with WiFi enabled. There goes more of your money.
Maps use edge if WiFi is not enabled. There goes a HUGE chunk of your money, $3 to load one map page. $1.65 to load one webpage in Safari while not on WiFi.
It is far cheaper in the long run to have a data plan. I can't tell you how many times in the beginning that I would forget and load up a webpage and get charged multiple dollars for it. Seriously, get the data plan.
