Well thanx to faquick and some developers there is a freeware application for the 7650 called PalettExtender. What the program does is unlock some hidden palette colours for your phone. Download and more info here.
[New] PaletteExtender for the 7650 (fw 4.xx only)
A little update, concerning people who cannot use it on v04.39:
It does not work on all handsets, it mostly works on firmware releases with major revision 4.xx, but in some phones with "operator modified" v03.xx it works too. And it seems not to work in some other v04.39 handsets. Unfortunately, if the program detects you that �your phone doesn't support this mode�, it will tell you so, and there's nothing you can do about it 😞
sorry about this
Another quick update: I am making some research, and it seems that even some handsets where the program says "not avalaible" CAN activate the other colour palettes. I am talking only about some v04.xx, NOT v03.xx
So, if you have v04.xx and pExtender does not work for you, please email me: [email][email protected][/email] and I will send you the next beta release, when avalaible (I don't think it will happen before tomorrow)
