My unlocked iPhone is working great after being unlocked, but before I start installing applications and making major changes, I want to be sure I'll have the option of starting over. I understand that restoring won't lock the phone again, and I'm fine with that - I'm not sure why I'd want to lock it again anyway. Can I do a software restore (with 1.0.2 at least) without worrying about messing anything else up? Is it as simple as running something like the "point and click activation" script after a restore to get back to an unlocked but relatively unmodified state, or would that even be necessary?

thanks
