What are the benefits of 2G+3G mode? Some of the advanced power control widgets or 2G/3G switching widgets allow the following options for the radio mode:


2G
3G only
2G+3G


What are the benefits of 2G+3G over running 3G only? Are there any drawbacks?
If you choose 3G only, you have no connectivity if you are in an area where no 3G is available. With 2G+3G, the phone will fallback to 2G if it can't get a 3G connection.
