How long can one video shot on an iPhone 4S be?

10 mins? 30 mins? 1 hour? What? I'm sure there's a limit. There's always a limit. I'm going to start filming makeup tutorials and need to know when I should stop the video and restart a new one as to not end up not recording parts of the tutorial.

How to get AppleCare for my iPhone 5?

I know when you purchase the iPhone you automatically get 1 Year Warranty. But my 1 year I believe is already up. So how do I purchase another year or two for my already bought iPhone? I tried going on the Apple website but they're saying that I need to buy the iPhone in order to get the warranty. Do I just go to an Apple store? Should I call tech support for an appointment or something?

Possibly moisture on my IPhone 4 lens?

I have had my IPhone 4 for quite a while and after school I walk to the car quite a distance, I have read recently that your phone being in your pocket when it rains can cause a moisture issue on your camera lens but at the time I had no idea. A couple days after that rainy day ( as i'm assuming this is the cause of my issue ) i noticed when trying to take a picture my camera lens was extremely blurry and nothing was really visible in the pictures. I looked at the lens itself and it almost looks like very small scratches and about 90% of the lens is covered with a very fine layer of what seems like crud. I'm assuming its moisture and not some kind of food or anything along the lines of that. The scratches themselves are too small to have such a big impact on my pictures that i'm getting. Is there ANY way that i can get rid of this issue without opening the phone? I've tried a damp cloth with soap, q tip with alcohol, microfiber cloths for glass lens, scraping it with like a guitar pick and nothing has come off and the size of the smudge hasn't decreased at all. A post somewhere else, a person said that there's no way the water could've gotten inside the lens so i'm also assuming the moisture is on the outside. I also think that it's been too long for the "phone in rice" trick to take off this smudge. It's happened approximately 3 months ago. I just didn't think it was really an issue and didn't do anything to figure it out or remove it. If anyone can help, much appreciated. Ty

Apple/iTunes help! Read additional details?

Hi, I'm trying to add a ringtone to my iPhone 4. While I was doing this process I was at the end and I got this message The iPhone "Mahmood Iphone 3g" is synced with another iTunes on "localhost". Do you want to erase this iPhone and sync with this iTunes library. Also it says An iPhone can be synced with only one iTunes library at a time. Erasing and syncing replaces the contents of this iPhone with the contents of this iTunes library.

Will this erase my contacts, text messages, photos, videos, apps etc. Please explain in a easy way, Not difficult!
