I have LG 2030 mobile. I was using the usb cable for more than a year and I got to download at the speed of 1mb in 3 min. Now I accidentally switched to serial cable and can able to download at the speed of 1mb in 2 1/2 min.
Using the usb cable it was only 7 to 10 Kbps but after changing to serial cable now the speed is 10 to 14Kbps. Sometime the meter goes as high as 17 or 20Kbps.
I am using flashget to download any thing. I was told this is the best program to download anything from the web.
