How to fix some mysterious problems.

I have a completely jailbroken and unlocked iPhone 3g running the jailbroken 4.2.1 firmware. Is there any way I can put in my at&t sim card without at&t detecting I am using an iPhone and automatically charging me the extra $25 a month for data. Maybe some cydia package? I currently don't have a data plan, and don't want one. I'm fine with just using wifi.

I dont know but I got my daughter a 3G iphone and it worked great with wifi. 4 days later she tells me the internet doesnt work. The message she got when trying to reach the internet was "this device does not have a data package something or other" and the internet did not work. Which I am assuming you want anyway. So for 4-5 days the phone worked great, the jb worked great, text messaging worked great, wifi internet worked great. No phone calls from AT&T which I doubt they would do anyway. I dont think they could tell if she had it or not since no data was being sent/received through there service. I think you would be safe from what little experience I have had with that specifically. But maybe someone else has another idea/theory or knows for a fact what kind of issues you would/could obtain from it.

I personally think your ok. Hopefully someone will confirm or correct what we dont know about it for sure.

Good Luck!

There's this from the Apple website, but I'm not sure it answers your question: Using an iPhone without a wireless service plan

Aside from that, what does it say if you turn it on without a sim card: Connect to iTunes? If it goes to the home screen, you're good to go. You can just use it as a WiFi device.
