Apple released the iOS 4.3.5 software update for iPhone, iPad, and iPod touch today. This update fixes a security issue with certificate verification. The previous 4.3.4 update was released to fix a PDF exploit which was used by a jailbreak but this new iOS 4.3.5 update fixes a security issue that has nothing to do with jailbreak.
If you are non-jailbroken, you can go ahead and update but if you are on iOS 4.3.3 you shouldn't update to iOS 4.3.5 if you want to keep your untethered jailbreak.
Here are the details of the security issue from Apple:
Impact: An attacker with a privileged network position may capture or modify data in sessions protected by SSL/TLS
Description: A certificate chain validation issue existed in the handling of X.509 certificates. An attacker with a privileged network position may capture or modify data in sessions protected by SSL/TLS. Other attacks involving X.509 certificate validation may also be possible. This issue is addressed through improved validation of X.509 certificate chains.

iOS 4.3.5 Jailbreak Information
Yes, it is possible to jailbreak iOS 4.3.5 but you will only have a tethered jailbreak. So if you're on firmware 4.3.3 with a untethered jailbreak then hold off on updating.
