Can you jailbreak a jailbroken iphone (read more below)?

I've jailbroken my iPhone 4S a day ago with evasi0n. But it had a few bugs, like the weather and stocks app wasn't working. I've already downloaded a ton of stuff from cydia. Now that evasi0n 1.1 is out, fixing these bugs, I'm not sure what to do. If I jailbreak an already jailbroken, will anything bad happen?

No you can easily jailbreak it again

Open up itunes and click on your device (ipod)
Next click the button that says "restore" this will wipe out everything on the ipod and re install the stock Apple ios.
Then you can proceed to re-jailbreak and redownload your apps

Get openbackup from cydia, back up your cydia app in it to icloud, restore in iTunes, rejailbreak then get openbackup and restore your cydia apps on the iphone.

I recommend just getting a weather app from the app store lol

  • Twitter, password and email help! Read below I have the Twitter app on my iPhone, and I use that twitter, but I can't remember the password for it. So I tried to reset my password from the computer, and it sent the email, but I must of put my twitter on a different email account than my usual one, and I can't remember which account it is. Or the password for my email. So basically, I can't get on the twitter I use elsewhere apart from my iPod, and my iPod has now broken. What do I do?
  • More you use an app the more space it takes up on iPhones and iPads? I have an iPad and new iPhone 5 that I just got. I have rhapsody on both the same app and amount of music basically (iPad as seven more songs on app) but on the iPad the rhapsody app takes up 2.8 GB and the iPhone takes up 1.8GB. Why is that? The more use the app the more space it takes up even if you're not adding new content?
