It does have its problems. I go into one of them in some detail in a review today at CNET.com.au:
iXpand 3G: “Ask any iPhone owner what they hate most about the iPhone, and 95 per cent of the time they’ll say battery life. Three per cent will talk about Apple’s somewhat oppressive control mechanisms, and the remaining 2 per cent is split evenly between people who lie about owning an iPhone and Microsoft Windows Phone 7 Series marketing managers.”
