Hello,
I was looking at the Tata indicom ad. about a new 'photon' device that has a WLAN which can allow upto 5 users to connect to the internet via WLAN. The same can be done in mobile phones that are internet enabled and have a WLAN too. Simply share the internet (GPRS, EDGE, 3G) with the WLAN device and use it as a wireless router. If some mobile apps makers could pick up this idea and make a tiny application, it can save the users the need to buy new devices and have a handy internet source for some devices around.
