If someone blocked my number can I still snapchat them?

So me and my friend got in a big argument and she blocked my number on her iPhone but I need to get a hold of her it's an emergency. Can I chat her on snapchat even if she blocked my number? It still says she's on my sbapchat and I'm on hers, would she get my snapchats?

IPhone issues still under warranty, where do I take it?

So my iPhone 5s when I shake it is making a noise like a screw is loose in there and it's not the lock button or mute button loose so I would just not care it fix it myself but it's under warranty so I'll use it while I got it.

Why doesn't my iPhone 4S activate Siri?

Why is my voicemail taking so long to set up?

I was wondering why I never get voicemails and then I look and I haven't set up a voicemail yet and when I press set up voicemail it asked if I want a default or custom voicemail and I pick default and it says setting up voicemail but it never actually sets up and then it goes back to the set up voicemail as an option again. And I have an iPhone 5 iOS 7 why is it taking so long?

IPhone stuck on Guided Access?

My iPhone 4S just got stuck on guided access and I can't exit out of it. I have looked up solutions and most people say to do a reboot by pressing the home button and the power button. However the problem is that my power button is broken.

I have assistive touch enabled but it doesn't do anything to help reboot my phone. I was wondering if there's a way to escape guided access when I don't have a functioning power button? Is the only way to let the battery drain?

Is it possible to get an iphone 4s screen this cheap?

So me and my girlfriend having a argument over this thing that really doesn't matter but to keep it short: she brakes her phone, screen and backside gets broken, her dad who is a IT engineer going to buy new screen, backside and battery and he can't accept any other brands than apple and he can't buy from ebay. I ask why, couse i think ebay is really smart and safe if you pay safely. And she says her dad doesn't trust it. He ends up buying all the things from china and it ends up costing 40 €(withhout shipping included) and he is sure it 's100% apple stuff and all is brand new. It isn't really that important but i'm the guy that thinks it's okey to use fake stuff and buy from ebay. But is it really possible to get it that cheap and it's not fake and brand new?
