Problem in Bold 9700 after upgrade to OS 6.0.0.448

Question

I recently upgraded my Bold 9700 to new OS i.e. 6.0.0.448 .Overall the Os is perfectly fine, but one day later I found the problem which is a major and serious issue. The network is not working properly. I called up my service provider and they told me that in network connection options there should be 3 options "2G" / "3G" and "2G/3G" but i could not see any "2G" only options, which is the reason for the problem.
I am having the phone on which i can not make any communications . plesae help..
thnx in advance
