How far back does the IPhone store text messages?

Like for example: I've never deleted any of my boyfriend and I's text messages on my iPhone.
Has it stored the texts from the beginning of time? Like if I keep clicking "Load earlier messages" will it take me all the way back to texts from months ago? Or are they gone?
Also is there an app or something that can help me view all the texts at once instead of having to load every single page of texts? I like looking at our texts alot since he's away on deployment, and I want to see the ones from beginning of time.

IPhone 4 text message from Unknown?

I have an iPhone 4 running the most recent software. Today I received a text from one of my friends in our Group Thread. Right after that I received a regular text.

Is my phone messed up? I'm very confused.

Can the police trace a thief from a Visa card number?

The manager at the store where I work today had her iPhone 4S stolen by a customer who had just bought something using his Visa Debit Card. After she served him, he reached over the counter and grabbed her iPhone and run away. The transaction had gone through the till and the card was verified by the PIN number. The till printed out the entire 16 digit card number and the expiry date on a receipt which our store keeps for their records. Assuming the card isn't stolen, can the police trace the offender just by a 16 digit Visa card number and it's expiry date? Also, would Visa be willing to hand this information to the police without a court order. We also have crystal clear CCTV images of the guy stealing it.

Is the iPhone 4s 16gb enough memory?

I would hold about 300 songs or more?
for games, i'd have maybe 20 or more if i could find some good ones.
for pictures, i take a lot of pictures, but i'd end up putting the majority of them on my facebook so it wouldn't really matter if i had to delete them on my phone.
for videos, i wouldn't take a lot of videos, but if i did they'd go on facebook, so it wouldn't really matter.
is the 16gb enough?

IPhone 4S Not Connecting to Wi-Fi Network?

Starting today my iPhone 4S will not conect to my Wi-Fi. I've owned the phone since its 2011 fall release and have never had a Wi-Fi connection problem. Here are some troubleshooting ideas I have tried (all failed):

Turn Power On/Off
Reset Network Settings
Reset router and modem
Forget Network

It is not the network's fault since my mac and iPad are successfully connected with no problems. Any more ideas would be great!

How to purchase apps without money in the bank?

I had an iPhone 3GS and when I purchased apps was able to buy them through the app store without having money in the bank, I would then be billed at a later date…
I've now have an iPhone 4s and can't remember how you turn this facility on. It currently won't let me buy any apps as I have no funds in the account.
I think it was called click and buy but I can't seem to get it activated on my new phone.
Any ideas?

Why won't YouTube let me publish videos from my iPhone?

Everytime I try and upload a video from my iPhone. It does the "Preparing Video" and about halfway through a message appears saying the video couldn't be published. I just tried uploading a video that shows how to get the "Super Perks" and "Beauty of Annihilation" Easter egg on Call of Duty: Black Ops zombies mode. The video is 19:06 minutes long. I know it will post because I've seen 40 minute long videos.
