Have checked a lot of places but don't seem to find this particular model (fancy having two sim cards). Any idea who might be selling it?

If you fancy having two sim cards, you should check the chinese market, they were the first, and they are still the best when it comes to multi sim mobiles. i suggest you buy from aliexpress as it is a subsidiary of alibaba.com and they offer buyer protection etc. (i dont get any money for this recommendation)

have a look at http://www.aliexpress.com/store/product/HK-Post-Freeshipping-STAR-NEW-3G-Phone-i9220-MTK6575-Android-4-0-3-512MB-4GB-5/317454_558038436.html for exampel, an adroid 4.0 full 2 sim mobile. or you maybe fancy those outdoor phones ? http://www.aliexpress.com/wholesale/wholesale-ZTC-007.html?SearchText=ZTC%2B007&CatId=5090301&SortType=total_tranpro3_desc&SortType=y

HTC Desire V is difficult to find - but HTC official store in Fortune Tower does have it one stock. Other places seemed not to even have heard of it...
