Sorry for all my newb questions today - but I just got my iPhone last night and am having a few teething problems!

I'm trying to get the Mail function to work.
I have a btinternet email account which uses POP3 and also a hotmail account.
My BT one syncs from iTunes from my Outlook, but doesnt work. I get errors. I've checked through the settings which all appear to be fine, but I dont know if I'm missng something?
If anyone has a btinternet account and has it working, can they please tell me what settings they're using?

Also - How do I set up my Hotmail to work in Mail?

many thanks...
