Hi Thanks for all the info.. Few days back , for my desktop i bought a USB Modem from a cellular provider with a internet connection plan which costs me $12 a month.. It is very small beautiful device which you easily carry anywhere..If this can be connected to N800 also it would be great.. Not sure about the power supply for the USB port which you guys talk about..I am not able to understand some of these technical stuff..Just waiting for some miraculous solution which will make my N800 an all time companion to me..
