If you own an iPhone 4 and need to know how to unlock it as you want to use another provider then read on. Hundreds of thousands, if not millions of people in the UK signed up to lengthy phone contracts when the iPhone 4 first came out.
With the introduction of the iPhone 4S and subsequent new models all those iPhone 4’s went back into the market and started changing hands. This was great news for many people who now found owning an iPhone 4 affordable, unfortunately almost all of those devices were locked into a single UK network.
Because of this it was an absolute godsend that the GEVEY™ Ultra Sim Interposer was introduced and could show you how to unlock iPhone 4 devices.
