PHS300 personal hot spots from Cradlepoint: phone 3g to wifi converter

This gadget can take the internet connection from your phone, and turn it into an 802.11b/g network that you can connect to. If there are others around that you don’t want stealing your bytes, then the 64/128bit encryption should be enough to keep them secure. The battery provides full three hours to work

But its compatibility is limited to certain Sprint and Verizon products. They both have very strong 3G networks, but they don’t always have the best coverage area. Still, if you’ve got a Sprint or Verizon phone, this would be a lifesaver.
