Ever since Apple released iOS 4.3, many iPhone users have been reporting a noticeable decrease in battery life from iOS 4.2.1. While further releases tend to help battery life a little bit, users state that their iPhone battery life still doesn’t last as long as it did on iOS 4.2.1 and earlier.
Apple released iOS 4.3.3 earlier this week, and in addition to rectifying the infamous location tracking bug, the update was also supposed to bring battery life improvements. We conducted a similar poll a few days after the release of iOS 4.3.1, and the poll results still showed that iOS 4.3.1 battery life had not improved.
With the release of iOS 4.3.2 this late last week, and the new iOS 4.3.2 redsn0w jailbreak still not completely stable, some of you might not want to wait any longer for a stable jailbreak, or maybe you’re having additional issues with the new OS. Whatever the reason might be, you can downgrade from your current iOS version to an earlier version using your SHSH blobs on file.
It is important you have your SHSH blobs on file for the iOS version you want to downgrade to. If you don’t have your SHSH blobs on file for the iOS you want to downgrade to, you will not be able to downgrade. You can check which SHSH blobs on file you’ve got by launching Cydia and looking at the top of the Cydia homepage where it lists all your saved SHSH blobs.
Last week, the Gevey Team announced their SIM Interposer for the iPhone 4. This SIM Interposer would provide the long awaited iPhone 4 unlock or Baseband 2.10.04 and 3.10.01.
Although there was some speculation as to whether this SIM Interposer was legit or not, today a reader over at Redmond Pie has provided evidence showing an iPhone 4 with 2.10.04 baseband running on T-Mobile USA’s network using the Gevey SIM Interposer.
Remember the days of the TurboSIM, and how that was a popular method for unlocking the iPhone 2G in 2008?
Gevey, one of the companies that was a leading provider of those TurboSIMs has released a SIM Interposer which can unlock the iPhone 4 up to iOS 4.3 by force activating the baseband using the emergency dialer.
Shortly after breaking the bad news about the iPhone 4 carrier unlock for iOS 4.3, iPhone Dev Team member @MuscleNerd announced that they aren’t giving up just yet and are currently investigating a new method to unlock the iPhone 4.
This method, called the “NCK”, is the key generated by Apple if they were to officially unlock your iPhone. Basically, it’s similar to an IMEI unlock code, which permanently unlocks the phone…
At Apple’s iPad 2 Event earlier this week, one of the major improvements in iOS 4.3 was Mobile Safari performance.
The Dev Team just released an updated version of their famous Mac jailbreak, PwnageTool 4.2. This new version of PwnageTool allows you to update your iPhone to a newer firmware while preserving your baseband. PwnageTool is the only jailbreak tool to let you do that, even though there are manual ways to update while preserving the baseband using TinyUmbrella.
In short, PwnageTool is unlockers’ favorite jailbreak as it allows to keep the unlock alive while still updating the iOS.
The Dev Team was able to make a few improvements to PwnageTool, notably a fix for the iBooks problem we reported this morning…
The iPhone 4.2.1 jailbreak tool GreenPois0n has been updated to version RC6. This update brings support for the Apple TV and fixes emulators compatibility issues with GreenPois0n.
Since it came out last week, GreenPois0n has been updated several times, and can now also be used to jailbreak the Verizon iPhone. Although RedSn0w can also provide an untethered jailbreak, GreenPois0n still remains our recommended jailbreak for 4.2.1…
