I would like to switch my phone between EDGE and HSDPA+ speeds.
There is NO switch like that, if you want only 2G then simply set the phone to "GSM only" and it will only get the slow EDGE speeds regardless of what area you are in.
If you do not set the phone for GSM only then the phone will automatically switch to 3G/4G speeds if those speeds are available in whatever area you are in.
Whenever you are in a 3G/4G area you will see a little icon in your notification bar if you have not set the phone up for GSM Only
