I've been asked to come up with options to offer free ringtone downloads on a website. These would be actual free ringtone downloads, not "Sure, we've got free ringtones, but wouldn't you rather have these much cooler ringtones over here for $1.99?", but actual free-to-download ringtones. Is there a way to provide this in a relatively global manner? Is it as simple as providing a low-quality, 30-second MP3 that the user can convert themselves? Is there a service out there that provides this functionality? We're looking for options. Thanks.
There's different methods of starting downloads based on which carrier/phone you're using
Sprint - GCD(generic content descriptor)
Verizon you have to send an MMS
ATT - depends on the phone
Nokia phones need a DD(download descriptor)
The list goes on and on and on
Not really a simple problem to solve
ringtones vary by phone; some require MIDI ringtone, for example, but for most modern phones a direct download of a short mp3 file is sufficient

I would like to make an app which can slow down a user's internet speed. Is there any ways? It's for a gym sports events where whenever the runner is running on the threadmill and with their speed on the threadmill,the download speed of a file is changed. For example if the running speed is faster,download speed is faster. Is there any codes that are able to control the internet speed? I looked up on stacksoverflow but all is on simulator.
There are no public APIs for doing this. I would suggest that you instead fake the reporting of progress.
If it is your app which is doing the downloading then if you implement the HTTP/FTP/whatever communication yourself over TCP/UDP your app can insert delays; or it can just download at network speed to a temporary location and transfer it from there to the correct destination at whatever speed it chooses.
If you are trying to slow down standard apps like Safari you could add a HTTP/FTP proxy to your system, which rather than simply proxying slowed down transfers. If you don't want to write a proxy from scratch take a look at Squid or GlimmerBlocker (I think its source is available, its in Java, this proxy is a Mac ad blocker demonstrating a proxy can be used for more than just proxying).
HTH, Have fun!

With the new app-extension kit, I'd like to know if it's possible to build an app that tracks various usage statistics of other apps. For e.g., the no of times someone uses their calculator or the no of minutes spent on Quora.
This is a really nice idea to enhance the ability of iOS system. However, even in iOS8 this is unlike to achieve. Apple has offered so limited APIs for APPs to access other APPs. In those APIs, I cannot find any one to record other APPs' launching or closing. (Except you call that from your own APP so that you can record the time, but this is meaningless.)
In the official document for App Extension Programming, manager for APP is not a type that is mentioned in the guide. I'm afraid that you have read it and it cannot give you more help.
I tried to do research on the most detail list of iOS APIs to find whether this is possible. But since iOS5.0, Apple no longer provided the API diffs. Here is the search result.

I already have a fair bit of experience making rails applications, but I have never really tried to make an application with the use of a microphone. I don’t need to have video call, only voice, but I would want to control how many people could connect to a single call. Also I would like it to not have to do with actual phone numbers, but have a completely separate service like skype. Any help would be appreciated, Thanks!
This is not a trivial rails app, but just from googling I found Adhearsion
Check it out: http://www.adhearsion.com/
Adhearsion is a full-featured framework for the development of
applications which interact with or control voice communications.

I know I can't record a video while I'm on my phone in general and that if the capability existed or could exist that it would be a feature/option.
Are there apps that do this and if it can be done can someone help me get started code wise?
EDIT
Because there seems to be some confusion as to what I'm asking, I will clarify:
Are we able to launch phone calls using the iPhone regular calling feature and use the iPhone regular movie creating feature (the video camera) at the same time in an APP - as we know it can't be done generally.
Yes and no. You can't use Apple's built-in camera and phone to do it. But, obviously there are many apps (i.e. Skype and others) that use both camera and voice features in their VoIP implementations. So, it would take a custom camera and VoIP to accomplish this.

I am currently new to ios so I do need help in this. I am trying to probe the sandbox of an iphone to retrieve any data from an application such as contacts. From what I know, I need to have understanding of c/obj c programming and understand the features of the mobile with regards to sandbox. So for my questions,
1)How should I get myself started?
2)Are there any features of the mobile regarding about sandbox should I need to understand before proceeding? (Some examples would be great)
3)Do I need to create my own application such as an app that stores contacts to probe on(using XCode)?
4)Any critical information that I missed out?
Much help is needed. Thanks. This is for educational purposes
The sandbox is given to you by iOS, no need to set up or anything. The sandbox means that your app is limited in accessing system resources, specifically file system, documents and settings. It can play only in its "sandbox". But there is no mock like environment that you can use for testing.
For more info on the sandbox, check out the iOS Programming Guide.
