How to know if my iphone 4 is unlocked or jailbroken?

I just bought a phone. From craigslist and I took my simple mobile to cut it and I put it in and it sayys invalid sim card? Is it unlcked? The guy told me it was unlocked… He was using h20 wen I saw the phone… And it has the app cydia so that means its unlocked right? Help please… How much do they charge to unlock a iphone?

If it not accepting the sim, then it is locked. As for the jailbreak. I'm not sure. But try running the cydia app and downloading something that costs money. If it works then its jailbroken. Hope his helps.

On average depending where you go they charge 90-99 dollars to unlock your phone. And yeah it does sound like it is unlocked.

Cydia has absolutely nothing with unlocking an iPhone. Cydia is an app that you get when your iPhone is jailbroken, so yes yours is jailbroken. Although, I'm sorry I don't know how you can tell if your phone is unlocked:/. Although, I know you can do it yourself with a simple Youtube tutorial! Or, of course, you can pay someone to do it for you.

You can factory unlock your iphone in under 24 hours by yourself for only $3 on ebay her is the link:

Yes, you can get it factory unlocked.take a look here:

The phone has a custom firmware, and I have no idea where or how to get the firmware to properly restore the phone to. Any ideas?
