The SIM card does not give you 3G. The phone must support 3G frequencies to be able to do 3G. No Blackberry at this time supports 3G.
All at&t SIMs being issued today say 3G on them. Some older ones didn't. But you state both of yours do. They are probably the same. Now it is possible, something on your account was programed to only work with the new SIM number. And that could be the reason they are telling you to install it. But you are not getting 3G out of any Blackberry. It's just a label on the SIM.
well heres part email seems they are being decptive then?

This probably won't be much help, but I have to stick my nose in..
At work, when I got a new 8310 Curve to replace my 8700, I had to get a new SIM. Not sure if it was because it wasn't 3G or if it was because my old SIM was from the old "blue" network.
