Hey guys,

My 4s currently is in iOS 5.1 and I KNOW that the gevey sim ultra S is not compatible for that version yet.

Anyways as soon as it becomes compatible, as soon as I unlock it, will it remain unlocked forever? I mean whenever a new iOS updates comes out and i update it, will it still be unlocked?

thx in advance

only a factory unlock device will remain unlocked. Unless you know how to protect a unlockable baseband you will loose it updating firmware. like you did when you lost the gevey unlock option going from 5.0.1 to 5.1 firmware. learn about unlocks before you upgrade firmware and or Baseband ;)
