Ah OK, I have an 2gb data allowance, I've tethered before and they don't seem to notice, other than sending me a text if I get near my allowance but that happens if I use a lot of data on the phone itself anyway. So I don't think tethering/hotspot would be any different for me cost-wise.

Reflashing the phone is a bit of a pain just to get one application working. Maybe I will have to do that, although I'll see if I can gain anything from the other thread.

I think I'm losing the faith with the N900/maemo now... everything is so much hassle. It was OK at the beginning because it could do stuff other phones couldn't, but now, I just feel like going for Android where all these things are just easy.
