In simple terms, standby power consumption of 3G is higher than 2G?

Believe it's more per second but should be downloading quicker so overall erm not sure

It's more overall IF permanently enabled. Because even when it isn't busy downloading it is regularly searching for the best connection... but, yes, IF you only enable it when you actually need it (to stream video or view heavy websites, download large files, apps), then pondlife's logic makes sense.
On my HTC HD2 disabling 3G resulted in battery life of 2 1/2 - 3 days instead of 1. Despite still using 3 email accounts, twitter etc... On my BB Bold 9900 it also doubled battery times - but BB's use RIM's data compression anyways, so 3G is hardly needed at all.

Best to put a shortcut on the homescreen to toggle 2G/3G...

I don't think that 3G uses more battery that EDGE. You will see higher battery drain when both are turned on - you have two separate radios. 3G is used for data and 2G for making phone calls. If you turn off 2G or 3G you are back to single radio. If you have a good 3G coverage and your phone allows it you can turn off 2G/EDGE completely.

I have 2G turned off completely as 3 UK does not have 2G coverage.

ctpahhik, you are wrong. I can't link to sources right now, but you are.
