iPhone 4S Proximity Sensor Equipped To Feature Siri

iFixit disassemble the Apple iPhone smartphone 4S is equipped with voice control with password siri. We may wonder why Apple invested Siri on the iPhone 4S alone. Now the question is answered by iFixit, that lies at the 4S iPhone hardware owned. iPhone 4S equipped with LED infrared proximity sensors specifically designed to work with Siri.

Siri is one of the security features found on the iPhone 4S, and not owned by any other smartphone smartphones including the iPhone 4 and iPhone 3G. What matters is not the participation in the Siri updates on IOS 5, it is not possible at the Siri implanted into another iPhone series, as some hacker was able to do so. But at least there is one reason why Apple does not want Siri was in an older device.

Proximity sensors on the iPhone 4S is always in active state. Not like in the previous iPhone which type is active only when the process call. Making it useful for features belonging to Speak Raise Siri who work for detecting the distance phone with a user interface.

Apple iPhone OS Version 3.1.2 New Released

Thursday October 8 iPhone released an upgrade version 3.2.1 for its existing OS 3.1.The new OS also includes Xcode 3.1.2 and is free from some general bugs present in the previous versions like sporadic issue(wake up issue in sleep mode).
The greatest advantage of this upgrade is that apple is offering it as free upgrade and the OS 3.1.2  is compatible for all the iPhone handsets  and iPod-touch. To upgrade your OS you have to connect to a computer with internet connection and download the upgrade via iTunes. After plugging in your iPhone into computer just press the update tab .
The OS brings with it solution to the ’sporadic issue’ that prevents the iPhone form waking up from sleep mode, causes  device to crash during video streaming .The problem of interruption in network services which persists until a restart of iPhone .The bug of dubbed ‘comma mode’ in user forum discussion  has also been resolved .It now also supports the creation for web applications that are optimized for Safari browser of iPhone.
The upgrade size  is of around 200 MB. On one hand the upgraded OS seems to sort out the major bugs on the other hand it seems to extend the age old problem of ‘Limited Battery back-up’.The new OS seems to to consuming somewhat more battery than the previous version causing Diminished battery life.
Another problem with the upcoming upgrade is that of wi-fi. The Wi-Fi glitch problem still persists like in version 3.1. and does not seem to working fine. For users who use Wi- fi network regularly ,should wait for a while for another upgrade having a solution to the problem.
For iphone users currently using version 3.1 ,I recommend to upgrade it as a necessary upgrade required as it has sort out several of the bugs .The new version is definately an alternative solution unless next upgrade is released. To update your iphone  you need is to download the update via iTunes. But if you are using a jail broken iPhone, wait until the Jail-break for the iPhone 3.1.2 is released.

Review iPhone 4

Glass and stainless steel, still the apex of modern design. Though it might sound like I'm talking about a Manhattan skyscraper, I'm really describing Apple's latest iPhone. The iPhone 4 departs from the rounded corners and (literally) feel good design of the past 3 iPhone models and goes for modern, angular sharp edges. It's a thing of beauty to look at, though I'm not sure I prefer it over the iPhone 3GS. Maybe that's a gender thing; women are supposed to prefer soft lines, but being a tech geek I'm not typical-- I actually loved the Motorola Droid's incredibly angular design. But that's up to you, prospective buyer.
