    Last night I upgraded to 10.3 then I downgraded to 10.2.1 then problems started to occur. First eventhough I try, I cannot get any of my contacs working on the phone, names always disappear. And not there is a new problem, The sim card is not compatible, I can make calls but the network is gone. I checked all the security things about sim card and they are all unlocked.

    Check out the "Radio".BAR-File... else, I have no other hint... you might got a 10.2.1.xxxx but need the radio-file of 10.2.1xxx(x+1) if you understand what I mean... please write your whole 10.2.1.xxxx version number and let the comunity check the exact radio-file for you... besides, you have to write us your device SQN100-1/2/3/4
    Sorry, I have no other clue!

    Because u down graded from a higher OS, some of the old files my not have gotten over written. Reinstall the lower OS again.

    You did use an Autoloader to down grade right?

    Did you back up your phone before trying to install 10.3? If you did, you could wipe your phone and reload your data onto it.
