Huawei showed off what they're claiming is the world's smallest and fastest HSDPA USB modem, the E220, at CommunicAsia in Singapore last week. We don't know how long that claim will stand but it is, in fact, quite small (3.5 inches long) and fast (3.6 Mbps) -- and, while Huawei seems to mostly be playing up the HSDPA support, it also packs EDGE and GPRS compatibility, plus a nifty mini USB connector. No word on pricing or availability, as far as well can tell -- not that we're ever likely to actually get our hands on one anyway.
