Dear all, I was thinking to upgrade my iPhone 4’s firmware to iOS 5. However, since I have an unlocked iPhone (which I got from eBay) running iOS 4.3.3, a friend told me to jailbreak my iPhone on iOS 5 while preserving its baseband. Any ideas how to get it done?

Before you jailbreak iOS 5 beta on your device, you should backup your iOS 4.3.3 SHSH Blobs using either iFaith or TinyUmbrella so that you can downgrade it to previous firmware version. Then you can follow this step by step guide on how to jailbreak iOS 5 beta 3 using Sn0wbreeze 2.8b4. However, you should be note that this version of Sn0wbreeze offers tethered jailbreak only, which means you have to tether your iPhone into your PC and boot into tethered jailbroken state every time you reboot or power it off.
