It seems that there is 3g option (hidden) for 7024. I am wondering whether there is similar option for 7022. I can not find the file INIT.SMDKV210.RC using Root Explorer.
Why would you want froyo? And no source was released by coby so can't really mod it . But there is a CM7 out but I don't think it has very much functionality either.
I am just trying to find some solution to make the USB 3G modem work in 7022. I am not familiar with Android but it seems that Froyo has a 3g option? (As 7024 comes with Froyo)
