IOS 7 on iPhone 4 THAT USES STRAIGHT TALK?

Please answer As soon as possible:

i have just the iphone 4 and i use straight talk. I really want to download the iOS 7, but i don't know if straight talk will do something about it. I know someone who had an iphone 4 using straight talk, and their phone randomly updated and straight talk TOTALLY disconnected their phone… But they luckily somehow got it fixed. Will i be fine if i download the iOS 7 update?

***Please ONLY ANSWER IF YOU KNOW FOR SURE***

I dint think ST will disconnect the service, maybe apple servers was to busy and something happen with the update.
as you say it work again, so I guess, the update came true finally, that happen one time with my mac computer.

I'm wondering the same, but with mms and data.
I'm sure, the phone will work, but not sure about mms and data.
I'm using the sim swap with tmobile, and its working, so not sure to take the risk.
apple should let people modify APN, why they block it. I pay full price for my unlocked Iphone, and they are stoping me to modify it.
I guess is the last time I will buy an apple because of this.
