MDA on ATT 3G SIM card?

[theonlyone23]

I have an MDA that I would like to use on ATT's network, but I hear that they are only using 3G SIM cards now. This is not a 3G phone, so does anyone know if this would work? Would I need a new ROM, or would it "just work"?

Thanks for any and all help!

Bro-
I use AT&T and I can verify that the AT&T 3G sim works on a wizard...it works in my wizard! :D

I didn't have to do anything special. Hopefully you have a G3 so you can sim and super-cid unlock fairly easily.

P.S. Go Spurs Go! I do love Avery Johnson, though!

the 3G sim card might work, but getting 3G fast internet won't.

It works. I use a 3G sim as an emergency prepaid number and I make and receive calls/sms/mail/everything fine using EDGE. No different than using a standard SIM.
