Hi all, I'm testing several tracking applications that uses GPS intensively, and I've noticed that really iPhone is missing something in the GPS hardware... At the beginning, several users complained that doesn't work, and in effect the first times I was using GPS location services, all failed! For 1 week-10 days, then the problem was solved doing NOTHING!... (this can be also a firmware fix, but it's really annoying!) Altitude, it's not precise, some applications uses raw data and give 50-70m errors!!! The best are apps like EasyTrails GPS or MotionX Sport, that seems uses some kind of interpolation, but it's really a trick, and in case of MotionX this eat your battery like butter! EasyTrails it's a bit better, but still seems there are the classical +50m in some interpolations... (at least, are fixed, so the delta are correct, hehehe!) The best is if Apple will decide to make better hardware! iPhone is already the top phone at the moment, no comparisons, so it should be quite intelligent to keep the same Apple-standard also in this minor (or less minor) details.... (otherwise a low-class Garmin or Magellan will eat our iPhone, like they are doing for almost all the iPhone apps!) ideas? rumours? iPhone 4G?
