Hi guys, I have a jailbroken iPhone 4 running on iOS 4.1. Couple of weeks ago, I have noticed that Fring and other iTunes apps are not working on my device. I can’t use Fring over 3G network. This is unusual because most of my friend used Fring via 3G. However, their iPhone is running on iOS 4.3.3 and some are already on iOS 4.3.5. So, will I be able to fix Fring when I restore my iPhone to iOS 4.3.3 or iOS 4.3.5? Thanks.

On the other hand, regarding firmware upgrade, unfortunately you can only restore your iPhone to iOS 4.3.5 as the Cupertino, California-based Apple already stopped signing the iOS 4.3.3 IPSW. You can only restore your iPhone to iOS 4.3.3 if you have saved iOS 4.3.3 SHSH Blobs, which was created using TinyUmbrella, iSHSHit, or iFaith SHSH Blobs Dumper. Additionally, you also be note that you will not be able to untethered jailbreak your iPhone on iOS 4.3.5 as the exploit used in iOS 4.3.3 is not working on this firmware. But you can tethered jailbreak iOS 4.3.5 using Redsn0w 0.9.8b4. Anyway, you can download and know more about iOS 4.3.5 from this blog post.
