Could someone verify these steps? JB 3.0.1 to JB 3.1.2

[bradl]

I just want to be sure I have the steps right on this, as I'm hoping to do this in the next couple of days. What I'm looking to do is go from 3.0.1 (Jailbroken) to 3.1.2 (Jailbroken) on my iPhone 3G. So far, the steps I have are:

1. Transfer any purchases I have back into iTunes.
2. Backup the iPhone.
3. Restore to vanilla 3.0.1.
4. Update to 3.1.2.
5. blackra1n.
6. blacksn0w.
7. Backup the iPhone.
8. Sync Apps.
9. Done.

Luckily, I only have 5 apps from Cydia, one of which will be 'fun' to put back on (LockInfo). But this should be the steps to do this, right? I read some nasty rumours about going from a Jailbroken OS to one not jailbroken eats up about 500MB of space on the Phone, and didn't know if that was still true or not. So I want to be sure I have it all laid out right. If someone could just give the 'yay' or 'nay' on it, I'd appreciate it.

EDIT: I forgot to mention that this will be done on a Windows box. Win7, to be exact.

Okay.. so you're saying that I should backup my JB 3.0.1 phone a couple hundred times. Got that.

Update to 3.1.2 *from* the JB 3.0.1, right? According to various sites and Googling, this keeps that 500MB used on the phone.

If I restore as a new phone afterwards, that should blow away that additional 500MB of used space, I assume? and I should move that 3.0.1 backup, or the 3.1.2 one that is going to be created after the update?

The last three are obvious.

1. Backup
2. Restore (it will by default restore you to a fresh 3.1.2)
3. Now you can setup up your fresh 3.1.2 from backup or as a new
phone(I always go for a new phone).
4. Run BlackRa1n/Snow.
5. Now sync your apps music etc.

Thanks for this thread, was wondering the same thing myself. Didn't know if the steps I had were correct. Followed this thread and everything went perfectly.
