have purchased and unlocking from Iphone-unlocker-pro which works on v3.1.3. It uses customized Blackra1n. the thin I want to know can I use it up if it do not support my Modem app 5.12.1 or not supported. Please do help me out in order to sort the thing that I want to. It would be a great help. Thank you.

I have tried doing it by updation but as I performed I got to a conclusion that the screen says wait for reboot for 15minutes. It did not happen So I did it manually. But there was no change. I do not what went wrong. So basically the is the thing that did happen when I tried to sort the thing well. Do look out.

As far as I know there no such software yet available to make the issue to be sort out the unlocking solution. So it would be better that you look out or wait for the time being till everything is able to stabilize and sort the thing well. Do check out for the issue. Ihope this may then help and get the things to work well for you.

Jailbreaking has been demonstrated on 3.1.3 but not yet been released. So it would be better that you wait out for the released version that would then help you out to get the issue sorted. So do check out and make the things to work essentially well. I hope you may then be able to perform accordingly. So it would be better that you wait for the jailbreak

There is a alternative to get the things to work well for you. All you need to do is to do is to download some application from cydia this will help you out well for jailbreaking. So try to get the application downloaded well to the same and you may then be able to perform the task that you wants to. So do check out for the same.
