What is the Correct Way to Charge an iPhone?

When charging an iphone (or can be any phone), is it true that plugging the smaller end to the device then plugging the power-end in the power source lengthens the life of the battery, whereas the other way around deteriorates the battery? Or it doesn't matter at all? They say it "surprises" the battery.

Please whatever your answer is, I hope you could provide supporting documents to your claim or maybe just a technical explanation.

Just to make my question more clear.
First, plug smaller end, then power source -- OK
First, plug power source, then smaller end -- NOT OK
OR
It doesn't matter?

Slow Wi-Fi and Ethernet / Disconnections?

READ EVERYTHING BEFORE ANSWERING: I have AT&T DSL Basic (768kbps).

My AT&T Router/Modem has these times where speeds slow down from my usual 0.60mbps to 0.30-.45mbps for already a year now. I try using Ethernet on my laptop, but it displays the same speed I get when I'm on WiiFi. The slow downs usually stay like that for a week and sometimes they speed back up or either stay like that which I have to unplug the modem and turn it back on.

The router/modem overheats (I already blew a can of air spray cause there was lots of dust that came out). It also tends to disconnect each 10 minutes cause of the overheating.

Where I live, it's 106°. Could the heat cause overheating routers/modems (my house is fresh as we have the ceiling fans on)? If a lot of people are using their AT&T Home Internet around my neighborhood (lots of AT&T Home Internet Wi-Fi users in my neighborhood), could that cause slow downs with my Internet and over loaded networks? Also, does the overheating cause slow downs too? Why does it slow down so much? I can load web pages, but takes 5-10 seconds longer to open web pages. And why is my ping always high.

Things connected to my Wi-Fi daily: iPad mini, iPod touch, my sister's iPhone, sometimes the laptop. But they don't do intensive things. We just check Facebook and Instagram, but I know they don't take up a lot of bandwidth cause my sister is on daily and I do speed tests when she's on IG (loads lots of pics).

Did Apple stop signing iOS 7.1.2?

I recently unlocked an AT&T iPhone through AT&T customer service rand connected it tot mobile and when I tried to do a full restore to update to iOS 7.1.2 it said software invalid and I already installed the latest iTunes and I download the update through iTunes and online and didn't work. So did they stop signing that version or is it that unlocked iPhones can't update?
