iOS 4.0.1 Delayed Due to Jailbreak?

MaxdMerc, who is a guy working at the Apple Store, Lakeside (UK) has just posted on his twitter account that the next firmware Update (iOS 4.0.1) might be delayed as Apple is fixing patch holes used to Jailbreak iOS 4.

Guy in Apple Lakeside seems 2 think 4.0.1 is delayed as they r doing a fix 2 stop jailbreak that they have found. Dunno if true? 

This delay may be due to the upcoming jailbreak by the guys in the iPhone Dev Team who confirmed that they will release a Jailbreak tool for all devices (Including iPhone 4) on iOS 4 / 4.0.1 [via Redmondpie]

So, What about following me on Twitter or become a fan on Facebook to keep yourself updated whenever something happen like a Jailbreak, Unlock, or Firmware update?
