Supposedly helps the reception issue in iPhone 4 and may help 3 & 3gs, one way to speed it up without going back to ver 3 is to turn of the search function that is accessed by swiping left on the menu screen. it is settings, general

Cheers for the info Leeds, I have just got an iPhone4 as an upgrade and the 3g has been passed on to a family member. 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it
