IPhone 4s not connected to PC?

I jailbreaked my iPhone 4s a week ago & after installing some cydia tweaks it unable to only opens pics when connected to PC also not connected to itunes need help & advance thanks

You need to reinstall the iTunes launcher, and then you will be able to connect. If this still doesn't work, then the jailbreaking means that iTunes no longer recognises your phone, because the status of you phone has been changed. If this is the case, you need to either buy a new phone, or back up your phone. If you have no back up available, then you can't do anything. The back up files are in your iCloud folder, and there should be an option along the lines of "back up to this save". This will clear Cydia and you will be able to connect again.
Hope this helps

  • Why does my iPhone not stay connected to the internet? My phone is in a constant state of logging on and off of the internet and will not stay connected. I have an iPhone 4, I just updated to iOS 6, I've sync'd to iTunes, restarted my phone, turned off Wi-Fi and turned it back on, and even reset my home internet but nothing has fixed the issue. I'm also unable to update my apps, but thats another question. Anyone know what could be wrong?
