Apps on jailbroken iPhone won't start up?

I jailbroke my phone, exactly one week ago, I was chilling watching a YouTube video, then press the home button, try to get on another app and nothing was working.every app crashed right when I tapped it.cydia wouldn't open nothing. I turned the phone off and turned it back on and all my tweaks were gone! I don't know why now I have no tweaks and the cydia app is still there but it won't open no matter how many times I click it.

You must have a tethered jailbreak in which you must reboot through the computer. Only way to get Cydia to work again. One tweak I have on my phone is called "Fake Carrier". I named it "NO.OFF" so I would remember to not turn off my cell knowing I have a tethered jailbreak. Look up on YouTube how to jailbreak 6.1.3 and look for Sikemenos. He's the best!

Any pointers would be greatly appreciated.

  • Reminder apps. On start up of computer? Due to a brain injury I have severe short term memory loss. I'm looking for an app that will pop up a to do list when I turn on my computer. Preferably dated so I can fill in items on a "need by" status. Something that would not be to confusing, (another little side affect of the injury)
