Why is my iPhone so glitchy?

My iPhone has been glitchy lately. For instance, I would hear my text Tone go off an I'd check the phone and there would be no text notification displaying on the front screen. Or sometimes when I would turn my phone on I'd receive old-late messages from hours ago… How can I fix this?

How much would it cost to upgrade my iPhone?

I currently have an iPhone 3GS from at&t. I have had my contract since december of 2011, and I'm pretty sure the contract ends December of 2013. I want to upgrade my 3GS to an iPhone 5 when it releases, but was wondering how much that would cost(estimation). Do you think there would be some type of deal on the iPhone 5 for people who want to upgrade? I've never upgraded a phone before so I don't know how this works.

Best Place to buy an iPhone 4s, no contract?

I have already tried Craigslist and eBay.

Also does anyone know about any good companies who buy iPod touches (4th gen, black, 32 gb) for over $150? Thanks!

I'm stuck on a desert island, what should I do?

I decided to go swimming but quickly got lost, and took refuge on a beach. All I have is my iphone, a stick of butter and my pet cat Ferjanksaf. Ferjanksaf is hungry, and I don't know what to feed him. Also I'm stuck on the island, I don't think calling will work out here.

How does droid compare to apple?

So the only serious smart phone I've ever had has been an iphone. Next week I'm getting a galaxy note and I want to know how do I do basic things like load music, and buy apps? Do I have to buy them directly from my phone or can I do it from my PC like with apple? Also with iphone I have to update it once and a while through itunes, do I need to do that with droid?

Will Apple fix my iphone for free?

I had me iphone 4 for about 2 years or so, and my warranty has passed. But the main focus is I dropped my phone numeral of times as it is cracked on the front and back. But one night my alarm woke me up, so I looked at my phone to see what time it was and nothing showed. I can here when I get a text message or someone call but I can't reply because I think the lights are broke which don't allow me to touch the screen or even see it! But I had an appointment but the hurricane pass so it has been pushed back till next week. Will they repair my phone for free, or will they swap it out? If I do have to pay for either what will be the price? I figured I should get some sorta benefits from being with them so long lol.
