Ios 7 is still unlocked by my old Turbo Sim

Update 10-07-2014,
-Still Working with Ios 7.1.2


Today Morning I update my Iphone 4s from ios 6.1.3 to ios 7. I take a risk of updating my phone without knowing my Turbo sim will work with new ios 7.

But before this I want to tell you my old experience when ios 6.1.3 released. I wait for a new trusted  turbo sim for one month and buy a new turbo sim named "X-SIM" capable for ios 6.1.3. Then I upadte my iphone to ios 6.1.3.

 

 

 

 

Then I insert x-sim and enter county code and phone is activated. After few days I relised that whenever I restart my iphone I need to enter that country code again. This irritate me a lot. Then an Idea stuck in my mind why not I use the old turbo sim which I was using in ios 5.1. So I trun off my iphone, replace my X-SIM with the old turbo sim and Yes Yes Yes that was working and the best part is it was not taking any country code even when i restart my iphone, take out sim tray and re insert it, it completely unlock my iphone as it is factory unlocked piece.

Now when yesterday ios 7 released I was afraid to take a chance to update. And yes it is still working on ios 7.

If you have same story like me.... Please share here....
