You don't need your sim as long as your phone is already activated.

Edit: To clarify, if you're upgrading to 4.0 or 4.0.1 because you're not already on it then yes you will need your sim to activate the phone first

This got buried in the main thread so I'll try here:

I have a 3G on 3.1.3 and the 5.12.01 baseband. It's jb'd and unlocked now but I used that Spirit.Fix.Itunes.9.2 thing that was never officially released on comex's site (his still said not to update to 9.2). It was a link from the redmondpie.com site. It works fine but I"ve been a little paranoid that maybe someone screwed around with it and maybe left themselves a backdoor into the phone instead of merely overcoming the problems with iTunes 9.2. I installed Firewall IP to try and monitor traffic in and out and nothing particularly suspicious has happened that I can see so far, but I still worry a bit.

Should I bother with this new release from comex to be safe or just let it be since everything's working? And if I sync with iTunes, that doesn't sync it in a jailbroken state, right? Any restore I do would just restore it to non-jb status and I'd have to redo everything?

Lost the ability to Facetime after the JB. anybody else?
Try verifying your settings to make sure that the JB didn't merely switch off your Facetime setting. Happened to me once when I wasn't even JB'en but it's just a setting configuration switch.

nope, the switch isn't even there anymore.

Restoring and trying the JB again.Did anybody if the JB did anything to the baseband or anything?

Here's a major bug...

Many people are losing the ability to use MMS and FaceTime.

Two questions, have we gotten any official word whether or not jailbreaking on the iP4 is detectable.

Second, I've never had an iP4 before, how does a jailbroken iphone work with itunes, can you still backup and sync as normal.

What about if you want to restore from backups can you still do that?

Also if you decide you want to remove a jailbreak, after you restore your phone, can you still load from a recent backup, or will you lose all your texts and emails and stuff?

JB'ing is not detectable unless you tell/show someone that it is.
Yes, you can still do everything on iTunes as usual.
Yes you can still restore, however, your JB will not restore so you must re-JB.
Yes you can still restore from a backup no matter what (but JB is erased)

So to JB you have to activate with ATT? I have mine on 3.1.2, i want to goto 4.x but i cannot activate because i dont have ATT.
