Will update once I get back home from Singapore. This will be the a perfect example on why official unlocked iPhones are the only way to go.

Okay,updated the Aifontriji to 2.0.1 and everything went as expected. The unlock remains, which means the status of the unlock will remain for the duration of its entire life. Operational-wise, the phone IS DEFINITELY snappier, with dialpads and keyboard springing into action faster and keyboard taps registering instantly compared to 2.0.

All my apps, contacts, iCal, SMSes, everything is intact, I suppose the data is pulled from the backups done before.

But seriously, the best improvement about this update is the speediness of the whole thing. It is now as responsive , if not better, than the Aifonej.
