4.3 ROM for Galaxy S2

[VIRGIN KLM]

Touchwiz or not? I guess you'd have to wait a bit for 4.3 based Touchwiz ones for the official updates to roll out so other people can base their work on them. If I were you I'd find a stock based 4.1 ROM and update it for the time being (it's actualy the stock 4.1 ROM [the official update] rooted and maybe even able for overclocking [might need a costum kernel]). There's not realy a noticable difference with the newer APIs in 4.2.x and 4.3.x if you ask me especialy in Touchwiz based devices that the updated apps are not used either way. For the moment I'd install CWM on my phone as a start, one you do that and you do backup of your current ROM you ran little to no trouble having issues with your phone.
