Do you read more then one book at a time?

Not literally at the same time, I'm sure you know what i mean.

I'm reading two books right now, when I'm out i read a book on my iPhone and when I'm in I'm reading a physical book. So right now two at the same time. I'm thinking of adding a third because I'm just too excited to start it…

so what books are you reading? And can you tell me their genres?

How to stop iPhone from using cellular data for apps I don't use?

Recently, my iPhone 4 (running the latest ios7) has started draining battery extremely fast and when I went to check what was using cellular data (usually the biggest battery drain on my phone) several pre-loaded, undeletable apps I don't even use or want to use data with were using data, even though if I remember correctly they were not before. I know to stop them from using data you press the little on/off switch in settings, but for some reason when I do that the second I exit the settings page they go right back to using data no matter how many times I switch them off. Is there any way I can stop this, because it's really killing my battery life?

Do I need resistors to run a usb to this fan?

So I have a little project going, really simple. Just a computer fan that I will list the specs below and a usb 2.0 off of a iphone 4 cable.
I'm going to cut the phone charger to get the usb half and use the USB VVC +5v and the ground. I'm going to add a power switch as well. I have heard usb 2 chargers put out 500mA? The fan that I'm using only uses.08A at 12v. Do I need any type of resistors for this to not burn up the fan? I'm new to this so be kind. It seems as if the USB port will put out much more than the fan can handle.
Also if I'm just using the usb port for power and not data can I just cut the usb data+ and data- wires out of the equation? Also I want this to all be linear so could I just solder in some resistors into the circuit before the switch? What ohm resistor should I get?
Or if I'm going about this all wrong please tell me. This just seems like a simple circuit. USB to resistor to switch to fan back to usb ground.Do I need resistors to run a usb to this fan - 1 Added (1). Update: If the usb only provides 5v and I need 12v could I use a transformer to raise the voltage? I know a usb 2 can power this tiny fan, the question is how can I do it efficiently.

IPhone didn't receive text while it was off?

I was gone for 11 days and my phone was off the whole time. When I turned it on I got one text and it was from someone without a iPhone. I asked several people if they had texted me and they tolde they had. I was also supposed to get a couple text from people that I don't have their numbers. Is there any way I can find out the text that I didn't get.
