You can look this site unlock-zone.com get the unlock Xperia Ion. To get the code,you also need to specify the following details country it is locked now,network provider and IMEI number.Then they the give the unlock code.
Check out www.htccode.com , also you have some free codes given away on xda-dev by them. As far as I know this is the cheapest available online.
Just now i had unlock my xperia ion lt28at. very cheap just USD11.80 using AT&T USA Slow Unlocking Service.They said it will complete within 2-3 day. In my case just 1 day only.Good service check it at http://www.superunlockcodes.com this is the cheapest that i know..
I just finished a chat with AT&T Customer Service... Thought that since the Ion had recently gone on Sony's 'unsupported' list that I might be able to talk them into an Unlocked Bootloader. The lady I spoke with seemed to think I was asking her for information on how to 'Jailbreak' my phone. It's already rooted and I'm running the lt28h firmware with the lt28at baseband so I can get LTE and JB... But I'm looking at these KitKat builds of CM and I want. Does anyone have any suggestions for how I should talk to Customer Service about this? I can't help but think that I wasn't adequately getting the difference between rooting and unlocking the bootloader across to the lady I was speaking with.
