Problems with the ipad/iphone and my new website

Hi all. I've just finished coding up my first proper website and having tested it on all the browsers you can install on a windows PC I was hoping that things would go painlessly. Not so...

When I borrowed my friends ipad and looked the page took an absolute age to load. And sometimes it wouldn't load at all. After checking other websites etc I'm sure it's not the connection. I have some Javascript I had never used before, could this be causing the problem? Sometimes it looks like it's taking a long time loading the FB, google and twitter buttons. Do they cause problems on iphones and ipads?

Unfortunately my problem is made worse because I can't easily get my hands on an ianything as I don't own one myself and all the emulators/simulators I've found don't appear to be 100% authentic. So it'd even be useful if someone could tell me if they have problems too.

Can anyone help me out?
the site's at http://www.traditionalirishgifts.com

I'd appreciate it

Anyone fancy taking a look at the site and telling me how it works for them?

Particularly does the horizontal dropdown nav menu work? when you hover over Guinness Merchandise for example a drop down of sub categories is meant to appear.

Someone has told me it doesn't work for them
