iPhone Dev-Team has already confirmed that they will release Ultrasn0w 1.2.1. It will not only unlock all older basebands on iOS 4.3.1 but will also fix the signal-bars issue which was mainly experienced by those iPhone users who are jailbroken on iOS 4.3.1 with their old baseband preserved.This surely is an important update as users on Basebands 05.14, 05.15, 05.16 don’t have any Unlock available till now.
Here’s what MuscleNerd tweeted:
From his tweet:
@hyper_trio yes the signal bar is fixed in tonight’s update (even on those without currently unlockable basebands)
Signal-Bar issue do not depends on the lock or unlock condition but it depends on what baseband you have on your iPhone running jailbroken iOS 4.3.1 on it. Even if you do not rely on an unlocked iPhone OR you have got a factory unlocked iPhone, you will still face this issue if your iPhone is jailbroken on iOS 4.3.1 and have older baseband.
Those who do not rely on an unlocked iPhone will be able to use their iPhone to make calls and do text messages but will not be able to see full signal-bars until they use the upcoming Ultrasn0w 1.2.1 patch.
