Did you install ultrasnow from cydia?
You don't have wifi Internet to just open cydia and install ultrasnow?
You will need to restore to custom ipsw and most likely reflash the iPad bb using redsnow.
I had to take a break from being a vampire addicted to making this work!
I now have version 4.1 and modem firmware 6.15
So now I need to go where they have wifi and open up Cydia and install ultrasnow.
Is there anyway I can do it being tethered to my PC?
yes!No, you need wifi to get internet and load cydia.
Also did you install the ipad baseband with redsnow?
