Here's a thought...

My Nokia E61 can be used as a 3G modem via its Bluetooth connection. The very popular Nokia N95 does the same. But they also have WiFi. I wonder if it would be possible to create software that would allow them to become WiFi routers? I don't know enough about the radio hardware involved to know whether this is viable. I fear not, or somebody would have done it by now.

Lots of interesting devices now have WiFi - the iPhone, the iPod Touch, the Nintendo DS... Just imagine if I could just switch on my pocket WiFi basestation and give them all 3G connectivity. That would be exceedingly cool.

What's the nearest I can get to this - anybody know?
