XDA’s Windows Phone hacker supremo HeathCliff has done it again. Apparently, he has found an exploit which lets you enable interop unlock on your already developer unlocked or chevron unlocked Nokia devices. Remember, this is the first and only interop unlock solution for Nokia devices so use at your own risk. This is just the first step to make Nokia get neck to neck with other OEMs which already have interop unlock solution available on XDA.
If you have a Nokia device, please make sure you back up before you try this. Since this is a HeathCliff hack, I suggest you try it as soon as possible because there’s a massive chance that it will successfuly work.
Again, I suggest you backup before you proceed. For download and instruction, hit the source link.
