Hi, I have an iPhone 4 running on iOS 4.3.2 and now I want to update it to iOS 4.3.3 to use JailbreakMe. I have already downloaded the stock iOS 4.3.3 IPSW file and tried to upgrade through iTunes, but no dice. Instead, iTunes gives me "this firmware not supported for this device" error. What’s wrong with my device? Any tips? Thanks in advance.

Anyway, I am pretty sure that you will be glad to know that you will be able to get untethered jailbreak on your iPhone 4 with JailbreakMe 3.0 without updating its firmware to iOS 4.3.3 probably because JailbreakMe 3.0 supports iOS 4.3.2. So go ahead and use JailbreakMe 3.0 to jailbreak your iPhone 4. You can refer on this tutorial if you aren’t familiar with the steps. But before you jailbreak, you should backup your SHSH Blobs using iFaith tool.
On the other hand, iPhone, iPad 1, and iPod touch users who have already upgraded their firmware to iOS 4.3.4 or iOS 4.3.5 can use Redsn0w 0.9.8b4.
