I did install the hacked Flash Player, that which works only on Dolphin.
In fact, I hate Dolphin. But the support to flash is half-assed to say the least, 50% of the time I go to see a desktop versione of a youtube video, it has some problems: hangs, goes too fast, can't skip, It's a pain.
Is there any other better workaround available ATM? Non-rooted preferrably. At least to get flash working with other browsers.
Otherwise it might be soon that I have found a reason for rooting.
