14 DAY TRIAL // A 'tethered' jailbreak of iOS 4.3.5 has been confirmed as possible by downloading and installing the 0.9.8b4 release of redsn0w as well as both the 4.3.4 and 4.3.5 IPSW files from Apple.
With the exception of the iPad 2, all devices currently supported by Apple’s iOS 4.3.5 update are compatible with the redsn0w jailbreak tool.
The only problem is that it’s a ‘tethered’ jailbreak, meaning each time users reboots their device, they will need to jailbreak again.
Before anyone had even attempted to point redsn0w to the new firmware updates from Apple, iPhone Dev Team member Musclenerd had taken to Twitter to warn that updating to the new iOS version may cripple their jailbreak.
“Jailbreakers please stay away from today's iOS 4.3.5 update!”, reads a tweet signed Musclenerd some 13 hours ago.
In the meantime, some discovered that redsn0w can be used to jailbreak iOS 4.3.5, as long as they have an iOS 4.3.4 IPSW laying around as well.
“So those who really do want tethered 4.3.5 can use redsn0w pointed at 4.3.4 (except iPad2),” Musclenerd later wrote, after someone had contacted the hacker with confirmation that 4.3.5 was a go under redsn0w 0.9.8 beta 4.
To make it clear for everyone wishing to hack their Apple device, Comex’s web-based JailbreakMe tool is not supported on the new iOS 4.3.5, nor under iOS 4.2.10 for CDMA iPhones.
The initial release of JailbreakMe 3.0 supports the following configurations, and provides what is known as an untethered jailbreak, according to the iPhone Dev Team:
iPad1: 4.3 through 4.3.3; iPad2: 4.3.3; iPhone3GS: 4.3 through 4.3.3; iPhone4: 4.3 through 4.3.3; iPhone4-CDMA: 4.2.6 through 4.2.8; iPod touch 3g: 4.3, 4.3.2, 4.3.3; iPod touch 4g: 4.3 through 4.3.3.
In other words, those who are currently jailbroken on these firmware versions and devices and wish to continue enjoying the benefits of an ‘untethered’ jailbreak may want to stick with their configuration and not update to the latest firmware versions from Apple.
On the other hand, the updates Apple served yesterday are security-centric. Keeping your unit on an inferior firmware version may pose risks.
