Can i use another carrier for cdma iphone 4 if i jailbreak it?

So I have a Verizon 32GB cdma iPhone 4. I was wondering if it is possible to use another carrier like AT&T if I jailbreak it?

You will need to unlock it since your phone will be locked to your carriers network. You can use this unlock code generator to unlock your iphone

  • Use IMEI blocked iPhone on another carrier? (Read description first)? The phone was legitimately purchased by me at GameStop. The phone worked for a few seconds and quit on me. By calling 611(the AT&T wireless customer portal), it indicated to me that it's IMEI blocked. I'm using a GoPhone SIM card and was wondering if I could just use T-Mobile instead to use the phone. Edit: I was using an iphone 3G for about a year and then moved my card over to the 4s.

  • If I buy an iphone used from another carrier ad buy a sim card from my carrier will that work?

If I bought one of these sim cards and a used iphone 5 from another carrier would it work with my carrier?
  • How to Make My iPhone 4 CDMA Sprint work with my GSM carrier? I did not know what I was doing and bought a Sprint CDMA iPhone 4 when I actually needed an iPhone 4 GSM. Is there any way to use the CDMA iPhone on my GSM network. Gevey has some unlock solutions but I do not understand the terms jailbroken or unlocked. I want to learn how to repair iPhones but I'm totally new to this… Any help would be appreciated.
