thank you for your suggestions veronica
i tried winamp in the past, it has several defects, there is no equalizer in the free version and it is weird when creating playlists, it is very nice but considering that is not a free app, i wouldn't depend on it
about photoshop express, what is capable to do? does it require a internet connection? it seems that the direct competitor would be cameramx
i'm still trying to find a nice month calendar to use on a 3" screen, any recommendations?
tschommer: none of the guides i tried worked for this device(including the link you posted that i eventually found by myself

)
eventually i had to fight with the bootloader, the drivers required and the dlls that i didn't had and then just downloaded a img that was already rooted from one of the xda pages and used flashtool to dump it by using the fastboot option instead the flashmode
avoiding to do the extra 3 steps required to gain root access that required to install a previous firmware .42(200mb file) that could be rooted, root it and finally update it to .62 or .69 to retain root privileges on the updated phone
interestingly the phone still sees the firmware as .62 but supposedly i installed .69 boot.img according to the website
the result still is the same, system works rooted and allowed me to remove dumb apps like office suite viewer and other similar crap that came with the phone and asked to be updated each week or so
looking foward to do this with a samsung phone using the modified odin tool(i think it is called that way) because flashtool for sony is good but weird and a bit disordered
thanks for your time and help, even when the info was disordered, i managed to gain root access and retain the nice sony interface
