Unlike Goog maps, bing.. you DON"T need the internet, so if you use it for hunting or fishing in Bummm F Egypt like I do... the others don't work, as there are no towers to pull their maps down. I must have basemaps & detail maps (logging roads, etc) ON my SD card, 8 miles back on the great divide you won't get squat for a tower...

I turn all radios off (airplane mode), set backlight to lowest & bring an extra battery, lasts for many days.

Re. tower questions above.. 3 ways to get GPS signal
1. tower triangulation (location btwn 1/5 mile & 1/2) (poor) (No GPS chip in phone)

2. GPS chip in phone
3. Using both (TP2) (faster)

Faster yet:
And you can assist satellite lock in with progs "QuickGPS" which downloads all sat locations from internet every week & uses phone as a computer to assist fast GPS lock in based off anticipated/estimated satellite locations (from downloaded satellite tracking data). AND, using AGPS check box in settings/other

Wonderful explaination... thanks for sharing / educating.

Cheers!
