They will go unless your phone is backed up and you set it up via backup

Anything you've added should go when you 'factory re-set'.

They go of course. Its a reset.

Yes, Reset all settings means everything wipe out from you iPhone.

  • Will the MAC address of my iPhone reset if I reset my iPhone to its factory settings over iTunes? I have jailbroken my device and used terminal to change my MAC address so that I could connect to school's Wi-Fi. But when I wanted to change it to its initial number, I typed in a wrong value and it just messed up my Wi-Fi, I can't connect to Wi-Fi anymore. Wonder if resetting to factory settings would help…
  • Will my apps and pics remain on my iPhone once I switch network? I have an iPhone 5s on an o2 network but I want to switch my network to t-mobile, when I change the sim card to t-mobile (after unlocking the phone) will everything such as pictures and apps remain on my phone?
  • Whatsapp contacts - if they're onnm contacts am I on theirs? I have the phone number of an old friend stored on my iPhone and they also show on my whatsapp contact list… Does this mean that they still have my phone number stored in their phone and also have whatsapp installed on their phone? The chat thing says they haven't been seen since 28th sept? If they didn't have my number on their phone would they still show as one of my contacts on whatsapp?
  • What settings will it change if I press reset all settings on my iPhone? Also, will this help speed up my iPhone because that's what I've heard. Because my iPhone has been so slow lately and taking like 3-5 minutes to send 1 text. If you know of any other ways that could help speed that up please also let me know that.
