Update : As we expected below, Apple has released iOS 4.3.4 to patch PDF vulnerability in Mobile Safari exposed by JailbreakMe 3.0. Likely Redsn0w 0.9.6rc17 and PwnageTool 4.3.4 will be released within few hours, stay tuned.
Remember JailbreakMe 2.0 last year which jailbroke iPhone, iPod, iPad up to iOS 4.0.1. Apple has patched it after just 10 days from releasing JailbreakMe 2.0. Wall Street Journal reports that Apple acknowledged JailbreakMe 3.0 exploit which used to jailbreak iPad 2 as well as iPhone and iPod touch, so that Apple is working now to release iOS 4.3.4 to patch JailbreakMe's PDF exploit.

Jailbreak iOS 4.3.4 untethered possibility :Likely Apple will release iOS 4.3.4 only to patch the PDF hole only, so we highly expect that the only loser on this upcoming update are iPad 2 users, as iPhone, iPod touch and iPad 1 users will be able to get untethered jailbreak iOS 4.3.4 by Redsn0w, Sn0wbreeze or PwnageTool.
Our recommendation :
Specially iPad 2 users, stay away from this upgrade to keep enjoying iPad 2 jailbreak. You also should save SHSH blobs for iOS 4.3.3 before Apple closes it.
iOS 4.3.4 release date :
Likely Apple will take the same duration that has been taken to patch JailbreakMe 2.0, so we expect that Apple will release iOS 4.3.4 between 15 to 20 July. Any way let's wait and see.
