http://forum.xda-developers.com – Hey, my phone runs with the doomkernel v14 and the gin2jb Rom since them are released, but i heard the Dixperia 2 Rom is some faster than the gin2jb rom. So back to my question, which one is faster, the doomkernel or the Lupus kernel and the gin2jb rom or the Dixperia 2 Rom? Sorry if i made some gramatical mistakes ^^ and Thx :) (HowTos)
