I recently (finally) jailbroke my iPhone 3GS (baseband 05.12.01) and everything is working fine! I'm very happy with the endless possibilities of a jailbroken iphone.
I'm not a jailbreaking expert and would like to update it to 4.3.3 without losing my data (including cydia apps and tweaks) is it possible? what should i do if so?
Should I update it via iTunes or through a custom IPSW (sn0wbreeze) or another way?
Also, my phone is unlocked and I read ultrasn0w users should avoid using redsn0w, so I can't jailbreak it using redsn0w right?
As you see I'm a still a newbie, so any help, suggestions and tips would help me greatly.
Thanks in adavance.
Honestly, given that you're using an unlock, I'd stick to 4.3.1. There are only minor advantages to 4.3.3, and the process tends to take some time and effort.
If you really need to go to 4.3.3, then the safest way is with a custom firmware from PwnageTool or sn0wbreeze, to make sur eyou retain your baseband. By doing this, all data will be wiped from your phone, then you'd use iTunes to restore. This will ''not'' restore any Cydia apps or data however. To do this, you need to install some additional software from Cydia before you start the update process. There are several backup apps, but I find PkgBackup to be by far the best (latest version even backs up SHSH blobs and AppStore apps/data if you want). xBackup is another recent one, but I've not used it. Anyway, you'd install PkgBackup, backup all your data to Dropbox, then create and restore to the custom firmware, do the iTunes restore, then install PkgBackup again in Cydia, and run the restore from that. Simple, right? ;)
