Can I update to iOS 4.3 now then jailbreak later?

[Hustler1337]

Hi guys,

So, I'm thinking of jailbreaking my iPhone 4 for the very first time (ever). BUT, just wanted to know if I can update to the official iOS 4.3 for now. I have downloaded the update from iTunes but have not yet installled it. But will installing iOS 4.3 mean that I wont be able to jailbreak when the 4.3 Jailbreak is released?

It's because I've read a few sites quoting this:

As always, I give my standard warning not to update and wait for the jailbreak release. This time, I am giving some extra caution, however.

With 4.3 comes apple’s implementation of address space layout randomization (ASLR). In short, this will mess up the way mobile substrate works. You will need a new mobile substrate in order to use your favorite tweaks such as winterboard, sbsettings, bitesms, folder enhancer, etc. So you should definitely avoid 4.3 until an “official” jailbreak is released for it.

Now, I'm not sure who this 'BigBoss' guy is (forgive me), but should I follow his advice? Or am I just misreading something, or taken something out of context and this no longer applies?

Any advice would be appreciated.

Thanks.

Maybe, maybe not.

BigBoss might as well be part of the dev team he's been around since the beginning and writes many popular programs like sbsettings.

I would say don't update to be safe

Odds are you'd be fine, eventually. But it has taken a long time for some versions to be Jailbroken in the past.
Put it this way; is it ok for you to be w/o a JB for months or possibly forever?

Personally I took the jump. I understand the risks, but I have been thinking about dropping JB for a while now. Each new version of iOS has made JB less valuable to me. Frankly the only thing keeping me at this point was wifi tethering.

Don't sweat it. That post was intended for people who are JBed already. Your only danger in upgrading is a longer wait to JB until the one for 4.3 is released, as opposed to JBing now and waiting to update with the rest of us.
