You will have to ask Sprint if you qualify for unlocking.
Sprint will only unlock for use with foreign carriers.
You cannot use it with any other U.S carrier.

How to findout which carrier my iPhone is locked to...

I recently purchased an iPhone 3GS from a friend (student) who was returning from Australia. Before purchasing I researched on the internet and found that the model MX133 / MX134 available in New Zealand and Australia are unlocked or can be unlocked officially by the carriers.
Now I have received the iPhone (I am in India) and when I try to activate using Vodafone's Chip it says 'Sim not Supported'... Ok... That part I get....
But the problem is that how do I find out which Australian carrier this phone is locked to... So I can find out their terms and conditions to get my phone officially unlocked ?
iTunes is not very helpful in determining the same...

@wjosten - I got the phone from a friend studing in Australia (Melbourne) and he brought it from a retail shop there... (No Sim)
@Ingo2711 - Thanks, but it says activation required and to connect to iTunes.
I don't want to use blacksn0w, if I can get it officially activated / supported.
Can we not find out the carrier from the Model / Serial / IMEI Number or something?
You see, I have the same number for more than 12 years and I don't want to change it. (No number portability in India, yet. And my service provider Loop Mobile does not support iPhone)
So I called for this iPhone from Australia (Since I was sure that those phones were either unlocked or can be officially unlocked)
All I need to do now is contact my friend in Australia and ask him to register for unlocking with that service provider.

How do i change carrier on iphone 3? phone was unlocked

I have a iphone 3 that i want to switch over to another network. i have the sim from other network and the phone is unlocked, but cannot find how to change the carrier network over. anyone able to help?

You need to swap the SIM.
The SIM is stored in a little pop-out tray on the top (IIRC) of the iPhone.
There was a 'SIM Removal Tool' inside the box your iPhone came in but you may be like 99% of the rest of the population who discarded or otherwise lost the tool, in which case a pin or paperclip might be an alternative.
Pop out the tray (using either the Tool or a pin), swap the SIM and re-insert the tray and you should be good to go.

I bought my iPhone in Germany, how can I change carriers to be able to use it in the US?

Ask the carrier it's locked to if they'll unlock it. If they won't, sell it.

How to find out whether my Iphone 3Gs (OS version 3.1.3) is officlially unlocked ( factory unlocked ) or "made" unlocked ? Can I upgrade its current OS 3.1.3 to OS 5 even if my phone is not officlially unlocked ? how to up grade its OS ? what are there any better ways to do it ?
Thanks,

Depends wher you obtained the iPhone from and it's original supplier
If the iPhone is an authorised unlock ( approved by the carrier) or was
purchased from Apple as an unlocked iPhone updating the iOS
will have no effect on the iPhone and it's lock status
HOWEVER if the software has been tampered with to remove the lock,
updating the iOs will lock the iPhone back to the original carrier who holds the lock
To find out the status of your iPhone you could call Apple support
and they may tell you if the iPhone is locked or not and if it is which carrier

How do I change the default iPhone screen capture format to .jpg? I have an iPhone 5.

How do I change the default iPhone screen capture format to .jpg?
I have an iPhone 5 (but I'm sure users with other models would like to do this as well).
My online searches have not found an answer -- I did find a discussion thread that was essentially, "Why would you want to do that?" Those posts are not welcome! Not looking for a work-around, an intermediate step, or the need to change the file format on a computer, etc. Just want to hit the two buttons and have the resulting capture be a JPEG file.
Not interested in jailbreaking or using apps that require jailbreak -- Want to do this with a new phone.
Thank you in advance for any help!!

You can't.

How do you transfer music from iPhone 3Gs to Windows PC.

Old windows pc crashed. Do not have back up. How do I tranfers music from iPhone 3Gs 16M to new windows PC. 99% of music was ripped CD's.

The transfer of content from sources such as songs imported from CD is designed by default to be one way from iTunes to iPod. However there are a number of third party utilities that you can use to retrieve music files and playlists from your iPod. I use Senuti but have a look at the web pages and documentation for the others too, you'll find that they have varying degrees of functionality and some will transfer movies, videos, photos and games as well. This is just a small selection of what's available, you can read reviews and comparisons of some of them here:
Wired News - Rescue Your Stranded Tunes
Comparison of iPod managers
Senuti Mac Only (Currently only the beta version is iPod Touch & iPhone compatible)
PodView Mac Only
PodWorks Mac Only
iPodDisk PPC Mac Only (experimental version available for Intel Macs)
TuneAid Mac only (iPhone and iPod Touch compatible)
iPodRip Mac & Windows
YamiPod Mac & Windows
Music Rescue Mac & Windows
iPod Music Liberator Mac & Windows
iGadget Mac & Windows (iPhone and iPod Touch compatible)
Floola Mac & Windows
iRepo Mac & Windows (iPhone and iPod Touch compatible)
iPod Access Mac & Windows (iPhone and iPod Touch compatible)
TouchCopy Mac & Windows (iPhone and iPod Touch compatible)
There's also a manual method of copying songs from your iPod to a Mac or PC. The procedure is a bit involved and won't recover playlists but if you're interested it's available on page 2 at this link: Copying Content from your iPod to your Computer - The Definitive Guide
Keep your iPod in manual mode until you have reloaded your iTunes and you are happy with your playlists etc then it will be safe to return it auto-sync. I would also advise that you get yourself an external hard drive and back your stuff up, relying on an iPod as your sole backup is not a good idea and external drives are comparatively inexpensive these days, you can get loads of storage for a reasonable outlay.

Have you installed iOS 5 on your iPhone 3GS?
If not - then connect it to iTunes, and prepare yourself for a very big download!
It will give step by step instructions once iOS 5 is installed.
