I can't find my contacts list on iPhone?

I had this iPhone for a couple of months now and I finally decided to actually use it as a phone. I inserted my sim card which contained my friends numbers. And everything seemed fine until I couldn't find them o. O When I was using my old phone, whenever I saved a number I saved it to my sim card, not phone so I don't have to re-save them all if I ever change the device. So what's wrong now? What should I do?

I have an 8gb ipod touch right now, and i'm hoping to get an iphone soon.
i used up about 6 out of my 8 gb on my ipod mostly just on songs.
i was wondering, if I buy an 8gb iphone and upload my songs and stuff to it, will the 2 GB be enough for pictures and contacts?
or should I just go for the 16 gb phone?

Verizon iphone 4 texting problems?

I have an iphone 4 with Verizon and it is always resending text messages that I have sent hours before. It only does it when I'm trying to send that person a new message and they get a message that I have set before that. Sometimes they will not even get the original message I'm trying to send and I have to keep resending it. I have called Verizon and they told me to update my phone with the new towers because supposedly my phone was out of date with that. It stopped it for a little while but has started back up again. I updated my phone with the towers again(which they told me to do every 2-3 months) but the problem was not fixed. My boyfriend says he will receive a mass amount of texts from me at one time that are all ones that were previously sent. Has any one had this same problem with their iphone? If so, what should I do before I call and complain again and TRY to get a new phone.

Do I have iPhone thumb or repetitive strain injury?

My thumbs have really been hurting for a few months now, maybe about four at the least. It's like a dull and achy pain centered around the ball of my thumbs and they both click CONSTANTLY. More or less every time I move my thumb and if I try my hardest not to let them click, they get so stiff and really hurt.
In the mornings I've been waking up with them being very stiff and aching as well.
I have an iPhone and have had it for nearly 2 years and I've never had any thumb problems before it…
I use it quite a lot - I sent about 5000 texts a months if that gives you an indication! I'm never really off it to be honest - I have the Facebook, tumblr and twitter apps so yeah, constantly on it.
Is there a link between the two? And is there any way to stop the pain that wouldn't involve me cutting down my use?

How to get free iTunes codes?

I'm really low on money and I want some new games. I don't want to jailbreak my iPhone. I do use freemyapps but that takes a long time for new apps to be added. I've seen many videos of sites that seem to work but I have to take a survey that seems endless. Is there a way to get the codes for free without having to take a survey? Or a way to get credits faster on freemyapps?
