IPhone being tracked via Wi-Fi?

My brother found an iPhone5 a week ago at the mall and decided to keep it. (I know he's wrong for that ). He took out the sim card, turned off the location services & the findmyiphone thing. The service is now off. I guess the real owner took the service off. He connected it to iTunes and restored it to a new phone. Now all the data's erased. He connected it to our home Wi-Fi & now he's all worried that they could still track him. Can they?

Yes.

  • My iPhone only turns on via Redsn0w after being Jailbroken? I jailbroke my iphone and had a bit of a hard time, but I ended up getting it done. After Jailbreak was done it got stuck on the apple logo so I used Redsn0w to turn it back on. Ever since then everytime it dies/turns off, or reboots, it won't turn on by itself. I have to plug it in to the computer, pull up redsn0w and "Just boot"… How can I fix it so it'll turn on normally again?!
  • If my iPhone is being tracked by GPS not using any apps, how do I turn it off from my phone? Can I just turn off my location services or do I have to do something else? Will putting my phone on airplane mode do the trick? (the gps system is not using cellular data)
  • I'm being tracked through my iPhone? My boyfriend confessed that he has been tracking my every move through my cellphone. However, he did not say how… I recently bought the new iphone and I haven't synched anything because I'm afraid that there might be an app that he installed in my phone. I have no idea how to find out the way that I was being tracked? Can anybody give me some advice please?
  • How to tell if my imessages are being tracked? I have an iphone and i'm fairly certain my parents are tracking my messages sent through imessage. They might be using a spy software like teensafe, but how can i know for sure if they are and what program they are using? Is there a way to check?
