HI! Yea I as well have not been having problems and thabks mostly to the Crack community. Been 24 hours now runnin 4.5.0.77 nice and smooth on my 8330.
Hope there won't be any real problems just take your time to do a little reading and if you can't find it someone I can only guess will know. I had to register as a ty for having all of the guides avaible to non-members and I just felt like being social as I get throu the day.
