Difference Between iPhone Unlocking and Jailbreaking

Difference Between iPhone Unlocking and Jail breaking

There is a lot of confusion among several people about jail breaking and unlocking

Jailbreaking

iPhone OS uses two partitions – first on is the media partition and second one is the operating system partition. Music, movies, contacts, App Store apps etc. are stored on the media partition. This partition is usually the size of your iPhone’s memory capacity, minus 500-600MB for the OS partition. Because of the way that Apple have set up the iPhone OS, we can not do any hacking in this easily accessible partition. To hack the device, we must get into the OS partition. The OS partition, the space on the iPhone that Apple has locked us out of, is where the jailbreak lies

Jailbreaking is a process that allows iPhone and iPod Touch users to run unofficial code on their devices. Once you jailbreaked your iPhone you are able to download many applications, mods and hacks which are unavailable through the App Store but available via unofficial installers such as Cydia and Icy. Some of popular Cydia, Icy advantages are as on >> Winterboard (To install Themes), SBSettings (Faster Method to Manage iPhone Settings), Tricker3G (For running WiFi only App on 3G or EDGE), Cycorder (Video Recorder for iPhone 2G, 3G) and lots more

Is Jailbreaking Legal?

Yes and no. The legality of jailbreaking is very unclear. Most iPhone owners including myself think that since we own the iPhone, we should be able to do whatever we want with it

Apple’s lawyers think differently as they consider jailbreaking to be a violation of copyright

Why Jailbreak Your iPhone ?

  • install 3rd party applications rejected by Apple for various reasons (ie. nudity)
  • video recording (now available on the iPhone 3GS)
  • changing the look and feel by installing custom graphics and themes
  • free tethering
  • get access to cracked App Store apps for free (not endorsed by me, but still worth noting)
  • be able to unlock your iPhone

What If Something Goes Wrong?

It’s very unlikely that something will go wrong… If you have a problem, simply plug your iPhone to your computer, launch iTunes, and click “restore”. As I mentioned above, it will restore your iPhone to factory settings

What Is Unlocking?

Unlocking your device means to open up the iPhone’s modem to accept SIM cards from unofficial carriers. For example In the US, iPhone will not connect to any carrier other than AT&T, unless it is unlocked. Should you want to use your iPhone with another GSM carrier, you need to unlock

What If Something Goes Wrong?

Although unlocks can sometimes mess up your settings a little bit, they are constantly improved to fix errors and bugs. If something goes wrong, you can always restore your iPhone to factory settings.

In Short…

Jailbreaking an iPhone means that 3rd party applications can be installed on it (ie. apps from other developers than Apple). Unlocking an iPhone means that any SIM card can be used on it.
