That sucks, I bought my iPad in the US (couldn't be bothered waiting for iPad 2 and it was $100 off so why not) and of course I can't use the wall adapter here in Australia, so I've been using the iPhone one - I was wondering why it's been charging so slowly. So for a decent charge I have to buy an Australian iPad charger or a US plug adapter to use the charger that came with my unit 🙁 you always learn something helpful from random threads!
