Although HP didn't mention 3G connectivity on their Mini 1000 netbook, there is a very easy way to hack your Mini 1000 so you can use 3G.
Laptop Mag teared a HP Mini 1000 apart & found a 3G sim card slot under the battery. One of the users (dplxy) of the Pocketables forum has worked out that if you download a WWAN driver & slot your sim card into your machine you should have 3G up & running.
