An Apple spokesperson has already announced that the company has prepared an update that will close the vulnerabilities in iOS and implicitly the one used by comex in the jailbreak solution on jailbreakme.com. It is not known exactly when this update will be available, but it is possible that Apple will hasten its release considering the recent wave of criticism brought to iOS security. If you have not yet saved SHSH for iOS 4.0.1, then I advise you to download the Firmware Umbrella program from here and save the SHSH now while you still have time. Saving the SHSH can also be done on terminals that do not have jailbreak, so save the SHSH even if you have not jailbroken but you want to be able to do it even after the new update from Apple appears.
If you used this program to save the SHSH but it was saved on the PC but not in Cydia, then don't worry because Cydia updates the information about the saved SHSHs with difficulty. If you have not saved with this program and rely only on Cydia, then for more security I recommend you save with this program as well.
