Why are my texts taking forever to send?

I have a decent signal on my iPhone and none of my texts are sending. It will says sending on the top under the name of the person but it won't send. I have the Wi-Fi connected I don't know if that has anything to do with it but the messages won't send.

Added (1). All the people I'm texting live in the same state btw they aren't oceans away. I'm doing a software update now maybe that's the problem?

My iphone won't let me call a certain person?

I have an iPhone 4 and a few months back, whenever I tried calling one certain person it would take way longer than usual to start ringing and it would ring once, then do the "beep beep beep" noise and come up with "user busy". No matter how many times I try calling, that keeps on happening now. I've tried deleting the person from my contacts then adding them again, adding them to favourites and simply deleting the person from my contacts and dialing the number. None of them work. The person has no difficulty phoning me. I'm pretty sure I didn't change any of my settings and the person doesn't think anything has changed on their end either. The signal and everything is fine when I try to make a call. Anybody know what it could be or how to fix it? Thanks!

Added (1). Oh yeah and if the person has blocked me (accidentally, might I add) is this what would happen when I call?

Advice needed on tablets/PC

Hi, I really want to buy a tablet, but I'm not too sure on which one to buy! I definitely don't want an iPad (I've got an iPhone and an iPod and don't want and iPad because its too similar)! I want something that is more like an actual pc, so that I can do my work on it, something with Microsoft office? Maybe the surface is the one I'm looking for? I would also prefer if the os on the tablet was pretty new and quite cool, e.g. Android! Any replies will be much appreciated!

Can I insure a second hand iphone, as I have the original receipt of purchase?

Hi, I'm looking to buy a second hand iPhone 4s off a friend. After much research I have realised it is hard to insure a second hand iPhone as it does not have the original receipt. But this one has, and therefore I'm trying to find out if I can insure it? Struggling to find the answer on Google which doesn't happen very often! Also, any suggestions to what company to ensure it with? Thanks.

Added (1). I should add that the receipt is in my friends name so I'm not able to insure the phone 'as new'

How to unlock an iPhone 3GS? - 2

I want to get a plan from Walmart that's $45 a month that's unlimited everything but they said I need to unlock my iphone before they can do anything. Can I just restore the factory settings? If you know how to unlock it or any other way that will work so I can get a plan from them please respond.

What should I do before a big fight?

This kid stole my iPhone today and ran off, I could catch up to him and he had three friends with him. I was on my own with my one friend who was too shocked to even chase the guy with me. Tomorrow I'm going to go find him with a few of my tougher friends, and we're first going to try to intimidate the guy into giving me my phone back, and if that doesn't work we'll have no choice but to beat the living hell out of him and his friends.

I'm not typically a violent person, and I haven't been in a fight in years. And I've never been in a premeditated fight. So I was just wondering how I should prepare mentally for the fight, so I don't get cold feet at the last minute, and I don't want to just stand back and watch my tougher friends beat them up.It'll give me a bad reputation and make me look weak, which will most definitely ensue retaliation. If you have any tips on how to prepare mentally (Or even physically), they'd be much appreciated.

If I hadn't mentioned it already, this is happening tomorrow.

Added (1). Going to a teacher or school administrator would only anger them more, rather than scare them. I'd end up being jumped later while walking home or in the hallway or whatever.

Scratches on my screen or screen protector?

I just bought the iPhone 5 and it has an otter box and a screen protector. I notice small thin scratches (they won't even come off with screen cleaner).Is it only my screen protector that is scratched or do you think my screen could have scrated that easy? Thanks so much! Btw I don't want to take the protector off to check because it is put on perfectly.
