Quad Bands Radio

[leungda]

I am having a question about the Radio.

I saw the radio thread. There are a quad bands radio. Now, My phone doesn't have UMTS 850 (no 3G support at North America no 3G Icon on the top of status bar). If I flash the quad bands radio, should I get the UMTS 850 3G support?

The short answer is no. The Euro/Asian Diamonds that came out were tri-band gsm and Euro/Asia 3g support. Later an update was released to make them quad band gsm. This was possible because the actual hardware was quad band, it was just locked down. The 3g chip is not triband, it is different in the different diamond models (NAM vs euro/Asian). So while you can make any diamond quad band gsm (if it wasn't to start with), you can not expand the 3g freq because the chip is not in your phone.
