Cleo,
Will you try
http://www.teenage-sex.mobi/ on your iphone and see if the right site comes up or if you see a blank wordpress install? If the mobile site does come up, let me know if anything looks screwy other than my overall design skills.
I've tested it with firefoxs iphone simulator and with the user agent switcher and it looks OK from here, but nothing works like the real thing.
Thanks.
