Unlock iPhone 4 to all networks?

I got an iPhone 4 locked to vodafone and i want to use it with my O2 sim card but Vodafone want to charge me £20 to unlock it! Is there anyway that i can unlcok it to any network without jail breaking? And without paying these weird websites…

Use this generator http://networkunlock.org/iphone4/

it will give you the unlock code you need to release your phone from vodafone

You can use AndroidUnlock.us

It says it's for Androids, but it worked perfectly for my brother's iPhone 5.

To unlock Apple Iphone 4 from Vodafone network lock, free unlocking service is not possible to get for this model. But you can unlock Nokia DCT, Samsung D500 and some brand old models using free unlock codes from online sites. For this costly phone, free unlocking service is very difficult to get. So i would suggest the site http://www.mobile-unlocker.com/vodafone-uk-apple-iphone-unlocking-service/rs2wp10/ get remote unlocking service and unlock it from Vodafone network lock. Then use with any GSM network sim card. In this method you don't need to jailbreak your Apple I-phone 4. This is permanent unlocking method and also very easy unlocking method. After unlock it you can use with O2 network sim card.

  • Will any Ireland Mobile Networks support L. T. E (4G) or iPhone 5? The question pretty much says it all. Does anyone know if any Irish networks (I know Vodafone and O2 are not) supporting LTE:4G data? Specifically for the iPhone 5. Leave the fanboy troll comments at the door, a simple yes/no specifics are what I'm after.
  • Is my iphone 4s unlocked to all networks? - 1 When i go into Settings > carrier and turn automatic off, i get a screen with a list of networks, eg o2 uk, vodafone uk, three uk, orange. Currently i have a vodafone sim card in the iphone on pay as you go, but i need to change it to a three sim card on contract. By the way i'm running ios 6.1 if thats any help
  • IPhone 4 has no Wi-Fi networks? So, whenever I open up my Wi-Fi thing it says there aren't any networks to connect to when I clearly have Wi-Fi in my house. I've tried entering the network and password manually, still doesn't work. I reset my settings, still doesn't work. I turned off my phone, still doesn't work. It's only my Wi-Fi that doesn't work, too. It works everywhere but here.So, WTF!
  • If I unlock my verizon iPhone 4 what networks can I use it on? I just bought an iPhone 4 off my friend for verizon, I was wondering if I unlock it what carrier could I use it on? Originally I wanted to use it on AT&T prepaid but I found out there's no sim car tray so I can't now I was thinking about using it on virgin mobile if possible. Plus does anyone have a link to where I can find out how to unlock my iPhone because it doesn't have a SIM card tray?
