My service provider is SINGTEL in Singapore and i believe singtel uses 3.5G network which the 3GS is capable of handling. The 3GS comes with EDGE too that is for sure. What i know is that EDGE serves the same purpose as 3G/HSPDA network right? Just that it is slower compared to 3G. So am i right to say that i could turn off EDGE and run solely on the 3G network? Because when i do that, i couldn't surf the net on 3G completely. could anyone care to explain? i am confuse. btw would the 3GS show that it is on a 3.5G network or it can only show "3G" on the carrier regardless whether it is on 3G or 3.5G network.
