Iphone 4s Wi-Fi and internet broken?

So my Wi-Fi has been broken for a while, but since i've already replaced my 4s twice and just happened to be up for an upgrade, I figured Id just wait it out. I didn't mind not having Wi-Fi since I have unlimited data and don't use it much. But now i can't access any internet connection at all.can't open safari, can't open facebook, can't even check emails. Called the sprint customer service, she couldnt figure it out(she was with me for about an hour) so i went to the store and that lady spent another 45 minutes doing everything i had already done to try and fix it. And of course, to no avail. So i went to apple, and of course they couldnt help me, in fact they said it was a 'user error' and wouldnt replace it. So I ended up upgrading early to a Galaxy(and so far, i have absolutely no complaints) but want to turn my phone straight back to factory settings and clear all data and information from it.

The problem, however, is i can't clear the 'wheres my iphone' thing in icloud because i can't access the internet and my Wi-Fi is already broken.

Does anyone know how to bypass that and do a hard reset? Or do i need to go back to apple and have one of their 'geniuses' do it?

Haha mines working and yours isn't!

Don't worry about it. Turn the phone in. Here's a question, why didn't Sprint just replace the iPhone?

  • Why does my iPhone still charge for Internet even when I'm not using Internet? So, I recently got a pay monthly plan with my new iPhone 4s. When i'm out and about I'm usually updating my twitter and Facebook account. But, when I'm put my phone down, 3G still says I'm using it and charging me. So do I have to turn it off when i'm finished? Or is there a much easier way?
  • Where can i buy broken iphones on the internet cheap? I just want to find some iphones to pracise repiring screens on, prefrebly a link would help NOT EBAY please thank you!
  • When apple replaces a broken iphone, do you get to keep the old broken one? The back camera on my iPhone 4s broke (just stopped working), so I called Apple and I have an appointment set up to replace the old phone with a brand new one. But, I want to know if when they give me the new phone, will they let me keep the old one? The phone still works fine except for the camera. In fact, it's almost perfect. And obviously I want to sell the old one on ebay to make a boat load.
  • My mom and i got the same phone and same plan yet her internet loads all the time and mine never does? Two iPhone 7+. Same unlimited data plan. Yet literally no matter where I'm, nothing that uses data loads unless I'm connected to Wi-Fi. Yet my mom's internet loads no matter where she is. It's even happened that we're in the same place trying to load the same thing and hers loads while mine doesn't. Yes, I have my data turned on. I've made sure all my data settings are identical to my mom's. So i really don't know what could be causing this.
