So, does the iPhone really have GPS? If yes, why does it need a phone signal to know where it is?
I think its assisted GPS iirc, uses gps, but then triangulates with phone masts for increased accuracy.
AGPS is the other way round. Gets positional/timing clues from cell data/wifi geolocation to get an initial position estimate that can then in turn be used to converge the GPS solutions faster (and more approximately) whilst more GPS fixes are acquired (which in turn narrow down the circle of error).
e2a: you can see this if you open (eg) Google Maps from a cold start. The blue 'circle of uncertainty' representing your position initially starts off quite wide (data from geocoding of wifi signals), then gradually narrows as mobile phone data, initial GPS and finally steady GPS lock (of several satellites) is obtained - the circle collapses to the blue dot (you are here).
“I used to ask Siri, ‘What are the five biggest lakes in California?’ and it would come back with the answer. Now it just misses. It gives me real estate listings. I used to ask, ‘What are the prime numbers greater than 87?’ and it would answer. Now instead of getting prime numbers, I get listings for prime rib, or prime real estate,” Woz says.
Worse, a lot of the time Siri says it can’t make a connection to the back-end servers that power the system. “With the iPhone 4 I could press a button and call my wife. Now on the 4S I can only do that when Siri can connect over the Internet. But many times it can’t connect. I’ve never had Android come back and say, ‘I can’t connect over the Internet.’”
The Android system also delivers better results, he says. “I have a lower success rate with Siri than I do with the voice built into the Android, and that bothers me,” Woz says. “I’ll be saying, over and over again in my car, ‘Call the Lark Creek Steak House,’ and I can’t get it done. Then I pick up my Android, say the same thing, and it’s done. Plus I get navigation. Android is way ahead on that.”
Another gripe involves battery life. “With the iPhone, something happened with the new OS or the new phone, and it just started running through the battery so fast,” he says. “I’ve had a lot of issues with things I have to turn off just to save the battery life.”
Bitdefender looked at some 65,000 iOS apps up on Apple’s App Store, coming to the conclusion that around 41 per cent of those apps could be tracking the location of their users without asking or letting them know. Even worse, around 18 per cent granted themselves the ability to look through personal address book data, also without asking to do so.
I don't know where this "track without approval" comes from. Any app the requires access to location services has to be approved by the user.
Impressive; though I'm not entirely sold on DLing an unknown third-party app which requires my iTunes ID / login credentials, which - in turn - are linked straight to my debit cardThe hack now works for OSX apps too:

B. Buy facebook pages with lots of followers apparently?Q. Hey, how do I generate traffic to my website when I've got no actual news?
A. Easy! Just knock out some artist impressions of made up iPhone designs and wait for people to post them up all over the place!
Yes, but they at least have to hold on to some grasp of reality, no matter how remote. Some of these artists impressions of 'upcoming iProducts' are the stuff that may as well go in sci-fi graphic novels."Pull some figures from somewhere, draw a statistically incoherent graph and use it to claim victory/death of company X/product Y in the next six months, in an article beginning with the words 'Industry analysts predict...'" is always popular. Industry analysts predict that in 2014 102% of blog posts will be like this.
One of my students has one of them massive screen phones, its ridiculous, he can barely fit it in the pocket of his skinny jeans
