Thanks for that response, Don S. I may possibly have a problem with my phone after the update. I can't seem to lock in my GPS and that's probably why I couldn't see the GPS icon. I went for a walk at lunch, turned on GPS and Google Maps and my phone would not lock into any satellites. Will have to check in detail at home this evening.
It is early days yet but my first recharge after GB update, gave me about 15 hours of battery life. With FroYo, I was getting 24-30 hours with the same usage. Will be monitoring this.
