not sure if this helps but I am on T-mobile and I get terrable reception at work, the main reason I bought my n900 was so I could listen to internet radio at work. I have the 3g , 2g selection utility installed and I find that if I switch it to 3g it somehow "forces" the phone to get a good 3g signal... by doing this I get 3.5 and can listen without a problem! turn it back to dual and it drops back to 2g with 1 bar and I get constant buffering. Maybe you could try the same on Voda?
