I'm looking at buying an iPhone 4s with a bad ESN on Craigslist. Can I just pop in a Gevey SIM and Straight Talk SIM and be all set? What is the best way of doing this?
I'm also thinking about buying a Sprint iPhone 4S (valid ESN though) but can I unlock it with Absinthe and use it with ST instead of getting a Gevey SIM? What's the benefit of the Gevey SIM vs Absinthe unlock?
