I have to make an international trip later this week. As I do not want to mess with the GSM settings in CM7 (I do not know how to make that work yet), I am planning on restoring my stock image. How can I avoid that the recently released OTA is going to mess up my phone (and unable root) once I am back on stock ROM? When the OTA announces itself, does it give an option to Postpone/Cancel instead of only Accept?
