How to access Wi-Fi without the password?

Last year I received the ip address, subnet mask, router, dns and search domains all under DHCP, as well as the server and port number. After entering all the information into my iPod touch 4th gen. I could access the internet. I tried to do the same with my iPhone but it says I still need a password. I know for a fact that I did not enter a password the first time, so what exactly is different between the two occurrences? Was the first time some strange, impossible fluke?

What would be the best camera and lens for head shots?

I'm not a photographer and I know absolutely nothing about cameras. One thing I do know is that my iPhone camera is quite rubbish for taking head shots.

I was reading this:
http://stepheneastwood.com/tutorials/lensdistortion/strippage.htm

and realised my photos always come out like 35mm, 24mm, 19mm. They change the shape of my face and exaggerate my features.

I'd like to start out taking head shots then move out to full body shots later on with a different camera. But for I'd like to buy a camera and lens to start out with. I want to make up for the lack of photos I've taken in the last few years.

If you could provide different options that would be great. Also would a camera that also record video mean a sacrifice in quality in regards to photos? Just wondering if I need to go for a camera that takes photos only. Looking spend under £500 as this would be my first camera.

From the article i read I gathered that 135mm lens would be the best to go for.

Is there an easier way to look at old iPhone texts?

IPhone 5S vs Samsung Galaxy note 3.Note 3 beating iphone in the future?

So a little time and youtube streaming made me lean to the iPhone with it's awesome operating System and awesome features like the touch sensor and the slow mo video capture, but it made me think with samsung's specs in the future can it do it also? If they develop a nicer O.S?

i've done research and i've found out that samsung has the overall advantage in terms of "horsepower" and size and apple has the advantage on terms of "skill" and looks, but i'm wondering because apple used less hardware but more software to make their smartphone more Nicer, but what happens if Samsung's customizability became much more futureproof? Is it possible that if a Custom Rom has been made for Note 3, then is it possible that in the future the note 3 would be much more beneficial in terms of practicality of buy? Or let me put it at this.
If samsung maked their software operating system android better in the future is it possible that note 3 can even match iphone 6 (air), because if samsung matched the performability of apple's O.S does that mean that iPhone 6 and note 3 would be just a match and iphone would just look more nicer?

Added (1). @Lvarg what i was saying was What if with samsung's higher performance specs. What if in the future they also develop an efficient O.S like apple has plus i really don't think apple is that efficient at all with 1500mah it lasts 10hours on heavy use yet with note 3 3000+ mah it last 30 hours heavy use, i just think iphones are overrated, You can play better games at note 3 btw android is open source you can download, customize and improve its content straight from the net, i believe iphones are for people who really only use it for normal texting, calls, games, etc. While note 3 is for people who knows how to push the capabilities of their phones.
