I mentioned Joikuspot a couple of posts back but it’s so useful I though it worth it’s own slot. Joikuspot turns many Symbian-based WiFi enabled 3G phones into a WiFi hot-spot, allowing a number of computers to share the connection over 802.11b/g wireless. For the brief time I owned an iPhone this is the one app that would have been a killer for me, sadly the nearest I got to this was rather cruddy iPhone proxy server that was hit and miss requiring a jailbroken iPhone.
So, the next time you are stuck in a hotel that has rip-off rates Internet connections you can pull out you phone and use your create your own portable hot-spot instead, perhaps even providing WiFi Internet to collegues too! The current light version is free but only supports a 13 digit WEP key, my guess is the premium paid version will support WPA etc.
They also offer a Windows Mobile\smartphone version called WMWifiRouterfor .
