Not too long ago I posted that the redsn0w 0.9.5 Beta jailbreak tool for iPhone OS 4.0 was available, well apparently according to an article over on softpedia redsn0w 0.9.5 Beta has been experiencing issues with 3G connection failures and SMS.
However the article says that the iPhone Dev Team’s MuscleNerd has now revealed an update to redsn0w 0.9.5 Beta to fix the bug issue and is redsn0w 0.9.5b2.
According to MuscleNerd, “For those JB app devs who experienced SMS or 3G data failures, the new 0.9.5b2 download at the bottom of this page should clear things up. You’ll need to do a fresh restore to stock 4.0b1 before applying the new beta redsn0w update.”
Of course this jailbreak tool is not for your everyday iPhone owner but is just for JB app developers and still only supports iPhone 3G and does not preserve carrier unlocks.
