Wow, a day after the iPhone Dev Team released their updated Redsn0w software, Apple releases an update to iPhone OS. This isn’t a significant update to the iPhone OS. It doesn’t introduce new and exciting features to the current hardware but it does fix a number of issues and bugs.
This update fixes and improves the following:
- Improves accuracy of reported battery level on iPhone 3GS
- Resolves issue where third-party apps would not launch in some instances
- Fixes bug that may cause an app to crash when using the Japanese Kana keyboard
This update is for all current hardware, iPhone 1G (EDGE), iPhone 3G, iPhone 3GS and all iPod Touch devices. You can easily get the update via iTunes by connecting your device and clicking “Check for Update”
*Note* It’s been confirmed by the iPhone Dev Team that Redsn0w 0.9.2 works with this new iPhone OS update only with iPhone 1G (EDGE) and iPhone 3G and *ONLY* if you don’t care about unlocking. Just point Redsn0w 0.9.2 to the iPhone OS 3.1.2 firmware IPSW — The iPhone Dev Team urges iPhone 3GS and iPod Touch users who wish to jailbreak to stay away from this update until further notice!

i bought my iphone 3g with firmware 3.1.3, but i tried to use redsnow 0.9.2 on it..when i try to load the firmware onto redsnow it says not recognized. HELP?
What IPSW did you use. Download 3.1.2 for 3G and use that.
Just last weekend, I bought a iPhone 3g jail-broken with 3.0.
It was first to me with Apple gadget, so I hadn’t knew about jail-breaking.
And then it was updated to os 3.1.3. so it has gone with GSM now.
I already did jail-broke so it has turned into like a iPod.
Until when should I wait for? or giving up?
I’m gonna be almost mad.
Apple does not looks like a giant but a kid, they never learn the lesson from the PC war. One day they will lost their growing.
