There is no box to check under Settings/Applications. My phone shows "Manage applications", "Running services", Development", & "USB settings". And I searched within each of options and still found no such check box.
I have a Samsung Galaxy S with Firmware version 2.2, Kernel version 126.96.36.199, & build number FROYO.UCKB2
Re-Posting -- Still unable to perform this. Looks like no one has an answer. Reckon I may have to switch to i-Phone.
