Jailbreaking the iPhone has always been crucial, giving you access to a whole set of features, allowing you to install tons of useful apps which otherwise wouldn’t have been possible, and most importantly, it also allows you to unlock your phone so that you can use it with any carrier. Apple of course patches all these loopholes in every new version of its OS which makes jailbreaking harder. But sooner or later, hackers have always managed to find new exploits which jailbreaks the iPhone on the latest firmware.
We can’t say for sure what the new iPhone 4.0 OS would be like, but we’ll know soon as it is set to be unveiled tomorrow at an event, tagged as “Get a sneak peak into the future of iPhone OS”. According to different sources, it does boast pretty neat features like Expose-like multitasking, and more. But at the same time, Apple is planning to raise the security bar, like always, we’re quite sure that Apple will try and patch all the possible known exploits to make jailbreaking the iPhone OS 4.0 a bit tough, not impossible though.
Spirit, the new userland untethered jailbreak, which managed to jailbreak iPhone 3.2 on iPad within 24 hours of its launch no doubt is the tool everyone is looking forward to, along with the solution which geohot has already demonstrated. The infamous iPhone Dev Team is also said to have an exploit (given to them by Sherif Hashim) which can unlock the latest 05.12.01 baseband.
While no ETA has been given for any of these mentioned tools, there is this talk going on in the community that they will be released once either iPad 3G hits the shelves, or when Apple releases iPhone 3.2 for iPhone and iPod touch. Now if these tools are released with iPad 3G launch later this month, all the exploits will be made public and Apple for sure will patch them up when they release the new iPhone 4.0 with the next generation iPhone. Once that happens, a new exploit will be required to unlock the then latest baseband on OS 4.0.
Now question is on whether it is worth making all these exploits public for a minor release like iPhone 3.x, or just wait for the next-gen iPhone with OS 4.0? Whatever decision these hackers take will be in the best interest of the entire community.
