Where you can get Sprint iPhone unlocked?

Anyone know where you can get sprint iPhone unlocked? I've checked most places and are either really costly or they can't do it. Please recommend some trustworthy businesses and if you recommend them please do it from experience!

I bought unlock for my iPhone at http://www.gsmfast.net They can unlock any cellphone at any operator.
They delivered very fast(I think it was 8 hours) and they are also cheaper than their competitors.
Recommended!

I don't think it's possible to do this with a Sprint (or a Verizon) iPhone (except maybe the iPhone 5), because Sprint (and Verizon) are CDMA carriers, not GSM - and only GSM phones can be unlocked.

The iPhone 4S for Sprint and Verizon does have a SIM slot, but it only works when the phone is outside the USA - even if you unlock it (all unlocking does is let you use a non-Verizon SIM when you're outside the USA).

And the iPhone 4 doesn't have a SIM slot at all unless it's an AT&T iPhone.

From my experience i would say you can unlock your Iphone locked to Sprint network here http://www.wickedunlock.com/apple-iphone/rs16wp9/. Here they help you to unlock your Iphone using remote unlocking method.
