iPhone 4S 6.1.3 jailbreak baseband question

[Miguels310]

I have a Verizon iPhone 4s 6.1.3 unlocked with Gevey SIM to T-Mobile on baseband 3.4.03. Model number MD279LL/A. I can't upgrade to ios 7 because my phone won't be able to unlock with Gevey anymore because the baseband will change. Since p0sixpwn has been released for Windows, I want to jailbreak but I'm scared that it won't let me unlock my phone anymore because the jailbreak might change the baseband.

Anyone have a jailbroken iPhone 4S on 6.1.3? Can you tell me your baseband, or any info on this?

The list of 4S basebands are here. If you're using the Gevey Ultra S SIM, it should be compatible with iOS 7.0.X.

As per your p0sixspwn inquiry, p0sixspwn works the same as Evasi0n and Absinthe, and does not require a restore process like that of Sn0wBreeze, so as long as you don't disconnect your device, your computer does not crash during the process, or you can't fiddle with the device during the process, you won't have any issues.
