You can still sync with iTunes, you just have to be VERY careful when the iTunes updates are going down. The best way to handle the updates is to undo the JB and accept the update when you are ready. Many wait until the update already has a new JB version in place. Accepting the update while still JB can cause some pretty annoying issues with the phone and should be avoided pretty much at all costs. Sometimes it will just install and knock out the JB, other times it can lock out the phone and you've got to get some heavier time invested into getting it back up and running again.
So in short, yes, still sync, but must watch for iTunes updates.
Jailbreak with greenpoison, get it here --> Greenpois0n.com.Ok, so it looks as if Jailbreaking your Iphone 4 is a good thing.
Simple, numbered questions....
1. Are we Jailbreaking with Cydia or with Greenpoison? Where do we get either of theme?
You can restore your phone back to factory using itunes2. Once you break (say with greenpoinson), can you bring your phone back to stock in case of warranty issues?
Yes, the apple app store remains3. Once you break, can you still use the Apple Apps store?
Not really sure at this time. But there are plenty of people with issues at this location --> Jailbreak QA4. What is the biggest worry when you Jailbreak? I mean there has to be a down side.
see response to #15. Where do we get Cydia or Greenpoison?
Me too, but it was very easy to do and so far no issues.Sorry, very new to the Jailbreaking thing. Feel like an infant when I'm talking about it.
