I was thinking of this app ever since I found out that you could toggle between 2g/3g connections (and that was the first day I got the phone when it was launched at the uk nokia store)

I think this is an excellent idea. Do developers really need convincing that such functionality is really worth consideration at all?.....of course it is..... come on now guys or girls....it'll be an absolute godsend!

The phone should default to 2g mode and when the browser is activated then it automatically switches to 3g. When the browser is closed there should also be a timeout then the phone reverts back to 2g mode.

some other fancy options should include that when a particular application is started, should it need to retrieve data from the internet, then a setting should allow the user to again automatically switch to 3g.

A tyical application which would be a good candidate for this functionality would be something like a stock trading program which constantly looks for live data feeds.
