Corelocation and assisted gps iPhone -

i have quick question, core location in ios 4.3.2 automatically use assisted gps or option need choose.

i working gps , recon settle time before finding accuracy(below 10 meters) rather long - few minuts.

regards

bjarke

it's automatic. best can check altitude, undefined when gps fix not available yet.

edit: see http://developer.apple.com/library/mac/#documentation/corelocation/reference/cllocation_class/cllocation/cllocation.html

if verticalaccuracy < 0, altitude invalid (from can infer no gps fix)
