With iPhone network lock , or folk still called the best iPhone lock should not update the latest iOS 7.1 at this time . The reason the current transplant sim does not support iOS 7.1 , so your computer after the upgrade will only use as iPod only, will not be calling and texting , not size waves . With the iPhone sim lock transplant is the only cure , if there is no sim sim transplant you will not give up on the machine to use , so please wait for some time to come , when that new generation is sim transplant update is not late.
Update on :
- It seems that only iPhone 5s is not supported , the machines themselves are 5s and test failed . Have you tried the sim on iPhone 5 and transplant success . And depending on network and SIM lock puzzle anymore .
- Some of you comment at the bottom of this article remain successful transplantation with iPhone 4s sim , so if you use the iPhone 4s can try .
Warning: iPhone network lock should not update iOS 7.1 at this time
