OS4 Safari google default search location wrong country iPhone 4

Hi there,
Small problem.. Safari in OS4 for iphone 4, I use the Google Search bar at the top which I like but for some reason it has defaulted to google.au (Australia) which is kinda annoying as im English and live in England and would like google.com results or possibly google.co.uk searches. I know I can change to Yahoo & Bing but I like google and i dont want to have to go to google.com manually all the time or to the bookmark of it. Is there a way to change the google search location in the top search bar to google.com without a 3rd party app?
The only reason I can think of is that my MacBook is from Australia and has an Australian keyboard layout hence I keep the Australian flag at the top for the correct keyboard layout for my computer. Although I have changed this to British, restarted and re-synced and i still get the google.com.au for Australia on the iphone4.
Any advice would be great, thank you in advance!!
