The iPad was not designed for the transfer of files over Bluetooth. You can read the supoorted Blutetooth for iOS profiles here.
You can transfer photos from iDevice to iDevice using Bluetooth according to the app description. But not from a Nokia phone to an iPad.
And you can transfer files from the iPad to the Mac via email, iOS file sharing, DropBox, and some other apps that you let you mount the iPad like a flash drive. It really depends on what you want to transfer.
