If you are looking to deactivate iPhone 4 look no further. There is one simple to use tool to deactivate iPhone 4 with ease, and it’s called iActivate. The iActivate lets users activate and deactivate their iPhones really simply.
It’s an official tool which has been made by the iPhone Dev team, so it’s a very trusted tool. The only catch with iActivator is that you will need an OS X machine to use it. So let’s hope you know at least one person that owns a Mac!
Update: iActivator is also available for Windows now.
There was another tool called iAsign. If you were familiar with this tool in the past, then you will understand what iActivator does because it does almost the same thing. The only difference is iAsign not easy to use, and iActivator is very easy.
iActivator was brought out back in 07, but developers have reported it to work fine to deactivate iPhone 4 and deactivate iPhone 4S.
Update: iActivator is also available for Windows now.
