Apple is tracking our location via iPhone, but why? [Video]

It is now confirmed that Apple is storing location informations of every iPhone users. Peter Warden and Alasdair Allan have found out that iOS have a database storing information of the location of iPhone and is taking a snap of the location almost every minute.

The picture which you have seen on top, is the location information store by iPhone from one of the creator of iPhoneTracker, who have create an application to let you import the location data that your iPhone is storing and displaying in a map format.

I have downloaded the software, and have load the map with my location information, and it is just pure amazing. It really did record down my whole Taiwan Trip on Oct 2010 and the more recent US trip on March 2011

Taiwan Trip 2010:

My recent US Trip on March 2011:

Interesting yeah? I have no idea, Apple can map my journey so well, it can almost be used as a proof if I ever have to show my location at any point of time. But why is Apple doing this? All this location information did not expire after almost 1 year. Why do Apple need to keep location information of their users for such a long time?

Apple have not gave us any information or reply on this issue.

iOS 4.0.1 is out! With new Reception Formula!

Apple released iOS 4.0.1 to better represent the reception issues. According to Apple’s PR iPhone’s Reception Bar Formula is wrong, thus they are showing more bars of reception than it actually have! With the new update from iOS 4.0.1, you will realize that your reception at home or in office will be much lesser than you had previously(this is what I felt).

Look at the Reception bars, it is really slightly bigger and longer compare to the previous version. I don’t think it helps at all for showing bigger bars, but maybe it is a mental thingy that I don’t understand. But one thing that I realized after the update is that my iPhone 3G felt faster and less laggy after the update! This I can’t confirm yet as I have just updated my iPhone 3G only 2 hours ago, but definitely feel faster!

I will post a update if I can confirm that this update actually makes iPhone 3G running iOS 4 faster.

Apple Confirm on Antenna Issues when you hold on to it, in a weird way

We have posted about users facing Reception issues when they hold on to iPhone 4 in a particular way, there are rumors saying that those users might be holding on to metal objects or trying to short the circuit of the antenna. But Apple just confirmed that this is a known issue that if User hold the iPhone 4 on the lower left corner in a way that covers both sides of the black strip in the metal band, shown on the photo above.

No doubt, lots of users have sent emails to Steve Jobs regarding this issues, hoping that he will reply. This is a action seems so popular in recents days, as it seems like Steve Jobs is replying to a lot of user sent emails recently!

This email was sent by Lucas, complaining on the antenna issue, and what did Jobs replied? “It’s not a big issue”!

In Regards to this Antenna issue, Apple also have officially acknowledged and responded to this iPhone 4 Antenna Reception problems:

Gripping any mobile phone will result in some attenuation of its antenna performance, with certain places being worse than others depending on the placement of the antennas. This is a fact of life for every wireless phone. If you ever experience this on your iPhone 4, avoid gripping it in the lower left corner in a way that covers both sides of the black strip in the metal band, or simply use one of many available cases.

Apple also mentioned that they will be updating the software of iOS 4 to resolve this issue, so we are not really sure if this is a hardware or software issue. Hopefully it is just a software issue, as it can be easily solve compare to hardware… [Gizmodo]
