GPP Sim and updating
I have an iPhone 5. And its locked to Softbank Japan and now I'm using a GPP Sim so that I can use it in the Philippines particularly at Globe's Network. And I want to update the firmware of my iphone to 6.1.3 from my current version 6.0.2. Was wondering that if I update, will it be locked down to Softbank rendering the GPP sim useless? And Can I jailbreak my iphone? Does it weaken the GPP sim?
Thanks in Advance, Nikko
