Why does my iphone's screen not show but it still functions?

I have a 3gs that still receives calls and functions with touch and calls and all, but the screen is blank. If i hold the home and power button together for a while, the Apple logo shows up for a quick second and the screen goes blank and the phone restarts (still functions after the reboot but screen is blank).So I don't know what the problem could be as the screen works perfectly when showing the apple logo, so now I'm confused. Somebody please help me

How long will my iPhone battery last when it is ONLY playing music?

I'm using an FM transmitter that connects to the iPhone directly, called the i Trip FM transmitter. I popped open the menu button and very slightly bent open a spot for me to put a coax cable into it to make a long range antenna. I amplified the signal, but I noticed when the iPhone is not charging through the i Trip's Blackberry charger, the range is literally twice as far.
So I want to know, how long does the battery last if the iPhone 3G is only sitting in my room playing music through an FM transmitter? Remember, the charger makes the signal worse so I won't be using it. I'll be leaving it unattended for the time I'm at school for a total of eight hours.

Also, any tips on increasing range? I'm buying a 5/20DB amplifier with a built in splitter to use for my FM transmitter and my TV antenna.

The FCC won't be an issue because I'm using 1) a vacant station, and 2) The signal cuts out between two hills and the antenna's max height is 18 FT aboveground (Broadcasting from my bedroom in the window sill) but the house is on a 20 foot hill, totaling 38 FT above normal terrain.

Last, is it good for me to get this much range out of a normal FM transmitter? Range is ~800 FT, and I calculated that one foot simulates 6.666 miles on a normal radio station. It provides stereo range until 650 feet from transmitter and starts fading out around 775 feet. It's then dead at ~810 FT or ~775 FT at night due to night DX.

Can my followers see what I search on Instagram?

So on Instagram for the iphone, you can obviously search like hashtags and users.
My friend and I the other day were searching her brother's username thing on Instagram because she doesn't have an iphone and I don't follow him. His instagram was private lol, but I also follow friends of his on instagram and they follow me.
So my question is, can any one of my followers see the users or hashtags i search?
or do they only see the pictures I like and people I follow?

Why won't my iphone update to ios 5.1?

My phone doesn't seem to have an option under "settings" to update. Is there another way to do this?

Added (1). I have an iphone 4. The current version is 4.2.8 (8E401).
My iTunes account is 10.1.1.4
I have never updated my phone before, but now some apps say I have to before I install them.
someone told me to go to "setting", "general", "Update software" - but I don't have an "update software" under settings.

Is 8GB any good for my needs?

And if i even add money to my iphone I might get Minecraft Pocket edition. So would it fit into 8GB and if so how much would be left back

Iphone 4s 8gb or 16gb? Do i have the patience?

I really want the iphone 4s. I'm tired of having a basic phone and i'm officially the only one in my family without an iphone. I do NOT have a job but i DO get an allowance (agreement between my parents and i being they will not let me get a job because of my crazy school schedule). I make 20 bucks a week and have been saving for the iphone for a few weeks now. I'm finally at $100 and am half way there but i looked online and i could get one right now, not as good quality or storage space but i could get it. So i need some advice. If i buy it now or $100 it will be an 8gb with a 5 megapixel camera, doesn't come with a few features like the iCloud, Siri, and the 500, 000 Apps in the Apple Store, and etc. The $200 16 gb comes with all of the features listed above AND an 8 megapixel camera. So it seems like the better buy but is it worth it? I mean.5 megapixels is great compared to what i have now, and i'm not really much of a picture person anyways.also, i have an ipod touch thats 8 gb and i havnt even filled all the memory with music or movies so i should be fine with an 8 gb phone, right? Do all the little things really matter? Is it worth the extra $200? I just want one like NOW and i don't know if i'm willing to wait another month and a half lol i'm sorry i know i sound so spoiled right now, but the thought of it being at my fingertips and me not accepting it is bugging me. I just need to know which is the better buy? Should i hold out or go for it now. Thanks for the help.

Added (1). Also, which color do you recommend? Someone told me white is bad with fingerprints but others say its not, and black just seems too boring to me… But i don't want to get it and regret which color i chose.experiences? Preferences?
