I have an iPhone 4S
model: A1387
IOS 5.0.1
Model: MD378LL
Carrier: Sprint 11.3
Modem: 1.0.13

first question
Is there a website which can really unlock my phone to sim free ?
I have no problem paying for that, just there are many websites saying they can do it and i don't know which one i can trust

second Q:
another thing is that my iphone is not activated yet (altough its not stuck on emergency call, i can see the regular screen)
can i activate it using redsn0w or any other program or i have to have a sprint sim card for that?

Thank you for your help!
