    Hi all, I just bought a unlocked LG Quantum C900 (AT&T, for T-Mobile use) and I have a few questions.

    If I update the phone will it become relocked?

    Will the phone get tge 7.8 update?

    a) If you are talking about developer unlocked, yes. It will relock. Carrier unlock will stay the same
    b) MS says yes. LG says ”no”. Others got it working: http://forums.windowscentral.com/win...8-now-yay.html

    I am now trying to update to 7.8

    LE: I got it! :D
    First, I tried the debranding + Zune... but nothing (LG Quantum AT&T, but I live in Romania).

    So, I've used the SevenEighter app and that worked superb. The app will crash after each successive update, and you have to reselect the languages (6 for me) existing on the phone before each install. But other than that, works just fine :) Got like 4-5 updates (I think from 7720) till 7.8.

    The app is here: http://windowsphonehacker.com/articl..._tool-01-31-13
