Data Killer

Downloaded this app., found it useful but it caused my data usage to increase exponentially! Even though I was in areas where I had downloaded the maps it was still causing my phone to download up to 40mb per day!
Struggled with it for a while then had to delete as AT&T is unforgiving with their data. Also very slow to aquire location via GPS when not near cell towers. Should also allow the satellite overlay to show through over water, not just land.
