I got problem with my Iphone version 1.1.2 by using nextsim, it works just fine but the next sim keep burned out (or maybe bad) 2 times.
Quesiont is if I upgraded to version 1.1.4 ( have not ugraded yet) and instead of using next sim, can I use the software to unlock the phone again ? if yes, then where do I find the instruction how to do it.

any input will be appreciated
