iPhone 4S 6.1.3 jailbreak baseband question

[Miguel Sanchez]

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?

Jailbreaking won't change the baseband but if you decide on restoring to remove the jailbreak, it will update to iOS 7.
