The Different Methods To Unlock An iPhone

Unlocking the iPhone is a process where the iPhone is modified to accept the SIM card of any carrier. Unlocking your iPhone is not the same thing as Jailbreaking your iPhone. When you Jailbreak your iPhone you are not unlocking it, rather opening it up to 3rd party tweaks and applications. For more information on Jailbreaking you can visit our Jailbreaking section. It is important to keep in mind however, that to software unlock your iPhone it is indeed required for it to be Jailbroken.

If you purchase an iPhone on a contract then it is locked to that carrier until your contract runs out. This is usually for a period of 2-3 years. When you purchase an unlocked iPhone, meaning you pay the full price for the iPhone, then it can be used with any carrier and there is no-commitments in the length you must stay with that particular carrier. What you should be taking away from this is that there is no real middle ground. You either have a locked iPhone or an unlocked iPhone. Thanks to some workarounds however, it is indeed possible to unlock a locked iPhone.

The first method to unlock an iPhone would be a hardware unlock (obviously out of scope for most people). At this time it is not possible to hardware unlock your iPhone. This entails actually modifying the internal components of your iPhone. When the original iPhone was released this was indeed possible, but long gone are those days.

The next method for unlocking your iPhone is a software unlock. The two software unlocking solutions for the iPhone that are currently available are UltraSn0w and BlackSn0w. UltraSn0w was developed by a group of developers by the name of the iPhone Dev-Team, where BlackSn0w was developed by an individual by the name of Geohot. The only problem with software unlocks are that they require a Jailbreak and are only supported on a limited number of older baseband versions.

Another method of unlocking an iPhone involves purchasing some sort of passthrough card or SIM interposer. When you purchase one of these special passthrough cards you will be required to place it between your SIM card and the baseband hardware (it essentially sits on top of your SIM card). In order to maintain this sort of unlock you must always keep the card between your SIM card and baseband hardware. This method of unlocking has become more popular because it supports newer baseband versions. Example’s of companies who create such passthrough cards include Apple N Berry and RSIM-7. The price of one of these cards is anywhere from $20 – $40.

The last method for unlocking your iPhone is an IMEI unlock. Although this method of unlocking the iPhone is more expensive than buying a passthrough card/SIM interposer (it will run you anywhere from $50 to $200), it is more convenient. When you IMEI unlock your iPhone it is unlocked for forever and you can update to new iOS versions, without worrying whether it will effect your unlock or not. IMEI stands for International Mobile Equipment Identity and it is a string of numbers which Apple uses to categorize iPhone’s as lock or unlocked. When you purchase an IMEI unlock for your iPhone it is placed into the latter category. There are many online services available for IMEI unlocking your iPhone, which you can find yourself.

Which iPhone Unlocking Method To Choose

Essentially you have three options when it comes to unlocking your iPhone.

Software Unlock Passthrough Card/SIM Interposer IMEI Unlock

The benefits of a software unlocking solution are of course that they are free. The obvious downfalls included limited iPhone generation and baseband support, as well as the requirement of being Jailbroken. The Passthrough card/SIM Interposer method is indeed better because it supports newer generations of the iPhone and newer baseband versions, but it isn’t always compatible with new iOS firmware versions. If you can afford it the obvious winner here is the IMEI unlock as it is not limited to specific baseband or iOS versions.

Software iPhone Unlock Compatibility

Unfortunately software iPhone unlocking solutions are no longer compatible with newer iPhone generations or baseband versions. If you happen to be in possession of an older iPhone with one of the compatible baseband versions shown below however, you can indeed unlock it for free. Keep in mind that if a new baseband exploit is found and one of these software iPhone unlocking solutions is updated we will update this list.
