OK, you convinced me! :)
I will go for a K810i flash. Just some further info, after the flash the phone will be a K810i in everything, and the identification of the phone (like pushing up & down volume button from stand by) will be K810i right? The patch I could eventually apply have to be for K810i?
To have the K800i light effect I have to change some file during the general K800-->K810 flash or after when the phone is already a K810i (the software to use it's always XS++?).
Thank you!
