I can't connect my iPhone 4 to itunes when it told me too?

Okay, so basically, I changed my password because everyone at school kept going on it. I changed it, and then I forgot it. So I tried to get into it, It was just a simple number password.
My iphone 4 is telling me to connect to itunes, so I plugged my iphone 4 in, and my laptop just said "Please respond on your phone to allow access" but I can't get on my phone to allow it.

I'm not sure what to do? Anyone have any ideas?

IPhone 3G stuck in recovery mode - Help! (REAL tricky for those iTouch geniouses)?

So my brothers iPhone 3G (unknown baseband, unknown firmware) was given to my after my smartphone died. I did not know if it was jailbroken but I knew it was unlocked and since he had a password on it he didn't know what the code was, I decided to recover it and reset to factory default. Big mistake.

So below I have listen all I have done, and still have no success, if you can offer any suggestions it would be greatly appreciated!

1. First, I tried restarting my computer, reinstalling (the latest version) of iTunes, and used all 3 of my USB ports as well as two different iTouch cables to connect to my PC (running Windows 7) to confirm it was not a program or device problem.
2. I was then told to try the reset through iTunes, no luck.
3. I continued to redsn0w (latest version as well as prior versions) to either jailbreak, just boot, and put into DFU as well as PWNED DFU and restore with a custom firmware. No luck.
4. I used snowbreeze to create a custom firmware (v. 4.2.1 iPhone 3G) and no luck through iTunes either.
5. I then tried iReb as I was getting both 1015, 1604, and 1600 error messages. After selecting iPhone 3G and/or fixing the 1015 error message through iReb, still no luck.
6. I've tried restoring to both 4.2.1 custom and Apple stock firmware, as well as 3.1.3 (as I heard it may help) but still no luck.

More info
I do not know the baseband or firmware currently installed, and my phone is stuck in recovery mode. I have done many different suggestions and no luck

Which is better? IPhone 5S or HTC One M8?

I have been thinking of buying a new phone. I'm very confused between the two flagship phones of Apple and HTC respectively, the Apple iPhone 5S and the HTC One(M8).
I really like both the phones, but don't know which one to buy. I'm not sure which is better in terms of the UI, the camera, processor, display and the build quality.

How to automatically switch from iMessage to Text Message for one recipient?

I'm working on a group project with someone. I had communicated with him in the past via iMessage. I've sent him numerous texts in the past couple of days and it sends as an iMessage. He hasn't been responding, which was unlike him. He finally texted me today (the project is due tomorrow) and said "if you've been texting me about the project, I don't think I've received them. I got a new phone and iMessage no longer works on my phone." He must have gotten something other than an iPhone.

I replied to him and it still sent it as a blue iMessage, said delivered and everything. I held down the message and said "send as text", which worked, but is there a way to get my phone to automatically do that for him like it does for my other friends without iPhones?

Added (1). Update: I just sent him another message and now my phone automatically sent it as a text. It must have realized that after switching the first two or something? Either way, it's working now.
