Jailbreaking iPhone 3G 8GB, firmware 2.2.1 baseband 02.30.03

[Tradewind]

I read both of the stickied guides at the top; one of them didn't apply since I have firmware 2.2.1 and I probably plan to use QuickPwn, and the other had only one guide on a board called iClarified that had a step I wasn't too sure about: the first step was to restore my iPhone, without backing it up or anything. I have lots of apps on here, and I seriously do not want to re-download all of them, so logically I'd think I should back them up first along with saved data and everything.
Anyone know of a step-by-step walkthrough for jailbreaking 3G 2.2.1? Or if the iClarified guide is applicable, some explanation on why I have to restore as my first step would be appreciated.
Thanks!

QuickPwn should generally work on your iPhone as is, but the general rule of thumb with jailbreaking is that 1) start with a clean install, and 2) stay with a clean install, don't restore from backup. This is to keep the filesystem nice and tidy, and combining jailbreak with a backup of your old files often casuses problems or just a slow-rinning phone.

Regarding the Apps, they should be on your Mac, and if not sync them on and they can be transfered back easily to a fresh installed OS.

Most personal data should be able to be synced from Address Book, iCal, etc on your mac - but alot of iPhone specific stuff will be lost. If your personal data is important to you, I would suggest that you jailbreak now, back up your /private/var/mobile/Library/ folder via SSH, restore to a clean OS, jailbreak that, then sub in your backed up Library. Not as complicated as it sounds.

If you want another guide, I personally like the ones on www.modmyi.com.

Good luck

Thanks. I ran into a problem at the very end:
I successfully finished the jailbreaking process using QuickPwn for firmware 2.2.1 iPhone 3G. However during the last step, the "please wait for your device to reboot in its newly modified state", it is simply stuck at the Apple icon, and keeps restarting every 2 minutes or so, and it keeps vibrating very loudly every minute or so. It has been stuck for at least 5 minutes (by time of writing this post). Is this normal or did I do something wrong?

I've gotten this problem before when I would jailbreak my phone, then restore from backup. I think it's been (un)cleverly coined the "spinning wheel of death" because if you look closely at the apple icon, you'll see the loading wheel. The only solution I can offer you (which is what I did) was to fully restore and rejailbreak the phone. Then, don't restore from backup. Instead, just create a new phone profile through iTunes and just resync all your data. As far as contacts go, I had all mine synced through Address Book (on my Mac) and through Gmail, just to be on the safe side.
Good luck, and let me know if you need some more help!

Yes, you'll need to redo it.
