I was told today it was 1000 mins I had but only swapped 300 of them and have not used any more on calls so its all very misleading and they said the swap feature is limited to 3g so I just don't know anymore. They advertise that swapping can be done as many times as you want once you have the mins which I do but they won't let me now as I have already swapped 300 mins for 3gs so confusion reigns. Thanks.
