    You must be kidding me, right? Omnia rom with the “trust of thousands of users”… As if that would be the only available option on the market. What about Cyanogenmod 11? The most stable as of now. With Gapps Aroma installer. Already tryed Omnia rom and is not stable as they claim…

    Please fix the “Get Daily Free Newsletters” popup for smartphones.
    It is MOST annoying on my S2 because there is no9 way to turn the thing off.

    Now back to a computer where I can see the X to turn it off,
    while on my Samsung S2 the popup is immovible.

    Thank you in advance…!!!
