Updating/Restoring A Jailbroken iPhone Help

It's very simple, just update in iTunes. Impossible to brick you phone, unlike Android phones, etc.

After jailbreaking on 4.1 with Limera1n/greenpois0n, you will notice a big change in overall OS speed.

 

Nope, that only happens if their is physical hardware problems with your iPhone. Restoring in iTunes is never a risk, 100% safe, no matter what was previously installed on the phone.

 

If you don't plan on taking a vacation out of country or something that requires another provider, then doing a restore and an upgrade to 4.1 will be fine for you. Don't erase from your phone. I mention this, because people think erase all settings won't force them to put their phone in DFU mode and restore.
Instead of doing a full recovery, you might want to investigate why your phone is slow. Depending on what you install in Winterboard, I've read of people who have slow running phones as a result. You might have better luck trying to narrow down your culprit.

 

So if im on iphone4 and 4.0.1 jailbroken. i just update to 4.1 no problems?

 

I'd use itunes to erase my phone first, because my luck is bad like that. Then I'd use itunes to update to 4.1. However, there's no reason you can't simply upgrade.

 

Sounds good ! Will do this once I have a little more time on my hands. Then stay on 4.1 for a little. Then jailbreak! Thanks for the help! Means a lot !

 

help!

i tried updating and an error occured. now my iphone is stuck in recovery mode and wont update, and is unusable!
