Happy Ending Story: Unlocked iPhone 4 iOS 5.1.1 Baseband 4.12.01 [Proof]

Unlock iPhone 4 iOS 5.1.1

I am Alex and I want to share my experience with you. I am a big fan of Apple and their unique and amazing gadgets. Few months ago, during my vacation in USA I bought an iPhone 4 from ebay.

Most of my friends have already used AT&T SIM cards, so I decided to use it too. I was satisfied and I enjoyed using my iPhone, but I didn't know that my problems would start when I come back home.

How I got stuck with my locked iPhone 4 ?

My iPhone became an ordinary toy, I have been using it only for listening to music, playing games, viber calls and relaxing with it sometimes. But this "toy" didn't have the most important property. I couldn't make phone calls or text and actually that is what makes this toy to be a phone. I started searching for unlock solution on net. At that moment my iPhone was on iOS 5.1.1 baseband 4.12.01 and it was impossible to Unlock AT&T iPhone.

One day, suddenly, I found this site — UnlockBoot.Com. This was the only one that wrote contents for upcoming solutions for all iPhone users who had the same problem. Since then, I've became a follower of this site and I visit it every day.

Unlock iPhone 4
iPhone 4 iOS 5.1.1 Baseband 04.12.01 Carrier 12.0

How was my iPhone 4 iOS 5.1.1 baseband 4.12.01 unlocked?

One day, UnlockBoot posted an article for OfficialiPhoneUnlock.co.uk which offers a factory unlock solution for iPhone 4. When I read that, I was very surprised and I decided to try it immediately. That happened on August 8th, 2012 and in a short span of time, I got a confirmation email from this service. After that, I followed the instructions posted there, I connected my iPhone with iTunes and I got confirmation message that my iPhone has been unlocked.

UnlockBoot gave me what I was striving for such a long time, and made me a more satisfied reader. I am glad I've found someone I can trust. I highly recommend this service.

Hi I'm John from the Philippines I have been wondering if the this officialiphoneunlock.co.uk is real because it has been 40days now and still the unit is still locked to softbank japan with 4.12.01 baseband since I had paid the whole price for the unlock for my unit. Please enlighten me what happen to my order unlock?

Ian Malepa

thank you so much my iphone 4 is factory unlocked


Nice work, i got my iPhone 4 locked on rogers Canada, unlocked after exactely 5 working days. Works like a charm.Although, it would be great if they lower prices a bit, except for the At&T which is kind of normal price.


i think this iphone is from usa probably at&t that supports factorey unlocking, nice try

i phone 4 with ios 5.1.1 and baseband 4.12.01 (NOT UNLOCK) without a original sim card...if you dont have the original sim card you will never find it...the things you can do is
: 1st wait for new gevey ultra sim(maybe it never came out for sell)
2nd unlock imei(its 199 dollars)
3rd wait for new ultrasnow application(because the old did not work)
if you dont do one of 3 options use like an i pod or say god to do a miracle.....i hope help you guys..sorry for my english...


This is fake. They got my money and dont reply on messages / emails. No unlock status available cause its not known. This is real bull....
