if I had followed Erica's 4 part guide with the unlock.app for mac that is on mod my iphone.com on my OTB iphone - can I upgrade to v1.1.1 safely? what do I need to do after that?
thank you in advance.

my iphone was never v1.1.1 it was always v1.0.2

i apologize if this questions has been posted before..if so please let me know the link?

everyone is asking about what to do if they anysim/iunlock but not Erica's unlock.app.
