Managed to upgrade my (LOCKED) 3G iPhone to 3.1.2, jb with blackra1n and then unlock with sn0w. Must be the EASIEST JB yet. Restored all my contacts, notes etc from itunes, runs actually FASTER.

Very very happy puppy LOL

hmm.

suddenly i can't run cydia on my maxis 3GS jbed with blackra1n.

it just says "loading" and dumps me back at the home screen.

looking online looks like some files need to be deleted. will try it out and let you know.

so here's what I did:

1) sync and backup my contacts and smses with itunes
2) do a full restore back to virgin 3.1.2 (if you're officially unlocked, no problem)
3) run blackrain
4) install cydia
5) DO NOT UPDATE cydia first
6) download and install Mobile Terminal from Cydia
7) update cydia as per normal

what i found is that, if cydia crashes it's probably due to some files which need to be deleted from the iphone (corrupted repositories, etc).

SSH into the phone and type "rm /var/lib/dpkg/updates/*" (without quotes) and hit enter.

Open MobileTerminal on the phone and type "rm /var/lib/dpkg/updates/*" (without quotes) and hit enter.

if all else fails, a full restore and reinstallation of Cydia will fix it.

Could be your Cydia installation was corrupted. If you're familiar with using Terminal (apt-get) you can try to fix it that way, but maybe a full restore and re-JB will be better.

make sure if you're updating cydia use the most RELIABLE connection you've got (signal strength). That should prevent any packages from being corrupted or interrupted.

if you just bought your iPhone 3GS from Maxis, it will come with the new bootrom which REQUIRES you to re-JB everytime you reboot.

I tried with a LOCKED iPhone 3G just now, blackra1n works without having to do a tethered jailbreak.

no such problems with my new 3GS (maxis set)

my 3Gs 32gb is one week old. new bootroom. mine works perfectly. maybe you need to reinstall sbsettings.

please do read the pinned threads carefully. if you DID you would know that the latest 3GS uses a new bootrom, which means you will need to re-jb EVERY time your phone reboots or your battery runs out. Keep your cable handy.

Yes you can, no problem.

as teikwing mentioned: read on TETHERED JAILBREAK

yes you will need to re-jb EVERYTIME YOUR IPHONE loses power.

Your data and apps will intact.

it means,YES you have to re-jb using blackra1n EVERY time your phone loses power or is switched off or is restarted.

minor inconvenience if you're with your PC/laptop most of the time.

I did that too, now when I go to cydia it displays - This Device has SHSHs on file for OS 3.1.2

Ok, noob question taim:

does that mean if I accidentally update to 3.1.3 on my Maxis 3GS, I can restore back to 3.1.2 and re-jb?

Ah MUCHO GRACIAS red queen.

I understand now. I'm curious to the same thing, but as of now there's no real reason to update to 3.1.3 so I'll stay there for awhile yet. I can't imagine iPhone life without SBSEttings and SMSHelper and ActionMenu.

Of course JB-ing voids warranty, but until they come up with a definitive way of detecting if an iPhone as been JBed before I would say the advantages still outweigh the risks. I can control my data usage, can control processes, can rearrange my themes and homescreens - all for FREE.

tried it out last night with my brother's DiGi Iphone, worked like a dream. Will try it tonight for my Maxis set.

My friend just told me this morning that Rock alerted him of a Cydia update- and when he tapped on it his whole phone just shut down. Maybe there's a vulnerability in Rock.
