1.1.3 vs 3rd Party Apps: To Update Or Not To Update?

If you make use of unofficial third-party iPhone applications and would like their presence on your phone to persist, refrain from updating to iPhone software/firmware 1.1.3 when it is released. Early indications are that this update not only disables any previously enacted open reading/writing of the iPhone filesystem (jailbreak) hence disallowing unofficial applications to run, but also makes it — currently — impossible to downgrade to previous iterations of the firmware/software that can make use of unofficial applications. As such, updating to firmware/software version 1.1.3 means you’ll be waiting for the development of a jailbreak method that works with the new firmware release or an ingenious method for downgrading to a prior release.
Previous iPhone software/firmware updates also temporarily disabled the use of third-party applications, but generally had allowed for easy downgrading to previous iterations that could be jailbroken until a new jailbreak method was discovered. Phones upgraded to firmware version 1.1.3 reportedly become non-functional upon downgrade attempts until they are re-upgraded to 1.1.3.
