Another version of iOS, another jailbreak. The iHacking community has been on a roll lately, releasing jailbreaks in record time for virtually all iterations of iOS 5, even throughout its months in beta. The latest jailbreak for iOS 5.0.1 is not without caveats however, so please read carefuly before continuing.

The latest versions of redsn0w and sn0wbreeze can be used to perform a tethered jailbreak for all models except the 4S and iPad 2. iPhone 3GS users may still enjoy being untethered, provided they have an older boot rom installed.

A tethered jailbreak means if your iPhone or iPad are restarted, the user must reconnect the device to a computer running a jailbreak utility. If the device is not plugged in at boot time, it will not boot into iOS
successfuly. This is opposed to an untethered jailbreak, where your phone or tablet can be freely restarted without any ill effects.

Despite the obvious shortcomings, BigBoss' semi-tethered jailbreak patch partially solves this problem. Verified to work with 5.0.1, SemiTether allows your device to reboot without being plugged in albeit with limited functionality. Users of this method can make calls, text and run third-party web browsers from the App Store. However, this somewhat liberating method also breaks certain features like the native Mail app, mobile Safari, jailbreak tweaks, most apps and Cydia. If this happens, the device must be taken home, plugged into a computer with redsn0w and restarted the old-fashioned, tethered way.

Another limitation are compatible models. Any iPhone or iPad running Apple's new dual-core A5 chip have been immune thus far to known jailbreaking methods. That includes the 4S and iPad 2. The iOS hacking community has admitted that working around the A5's on-die boot rom poses an enormous hurdle, but we can be sure there are people currently hard at work trying to solve this conundrum.

Well known iOS hacker, MuscleNerd, recommends, "Jailbreakers and unlockers should avoid today's 5.0.1 until a flow for downgrading to 5.0 is developed.". His concern stems from Apple's recent ability to "flip a switch" at any given time which could render existing, untethered jailbreaks useless. The old practice of saving your SSH blobs alone is not enough to guarantee you can restore your phone once this happens.

my problem is I have to select the image and then hit just boot every time just to boot it up. Is there a better option?

Yes. Wait for the untethered JB.
