Do you have constant amount of stuff lined up for download?
No, I'm not downloading anything, certainly in terms of music or video etc (whereas I was on my previous package), god knows what my usage would be if I was!
I'm not spending any more time on the net, I don't think I'm doing more (although it seems I must be), not enough to justify a doubling in usage anyway. It couldn't be something leaking could it, I don't know! I wondered if anyone else had experienced a similar increase.
I'll try the download you suggested anyway, thanks.
