Thx for all your answers.
You can backup all your data using Backup&Restore app.
To flash a custom rom you need root access and cwm (Make sure you follow the instructions carefully. Also, don't use cwm from another device except sola; Some root methods are universal but you have to take a look if they support sola and ics too)
Once you root your device, you can install cwm.
Once you installed cwm, you download the rom you want to flash (always be sure that's is for sola and not for other devices) and you flash it via cwm (to enter in cwm, press the volume down button once you see during the boot the Sony Logo; You have to press continuously the volume down button for 4-6 times.)
Before flashing the rom, in cwm, you have from the cwm menu, to wipe cache, dalvik cache(advanced menu) and personal data.
Notice also that if your bootloader is locked, you can only flash roms based on ics and gb, not those based on jb. (unlocking the bootloader, you will make you loose your warranty).
For any further help let me know.
