I POSTED THIS ON XDA A COUPLE OF WEEKS AGO AND NOTICED SOME PEOPLE WANTED TO KNOW ON HERE...SO HERE IT IS
Here is a small step by step guide explaining how to quickly switch ROMs on the xperia x10, for people that don't know how to.
As far as I know, this is the closest thing to a dual-boot, as dual-boot isn't possible atm, but it is very easy and quick to do
1) Boot xRecovery
2) Go to backup/restore
3) Choose Backup and wait for the backup to complete
4) On your SD Card, locate to xrecovery/backup and rename your backup to something you will remember, making sure not to have any spaces in the name, as this will show a mismatch error.
5) Now you can wipe the phone and install whichever other ROM you want.
Setup your new ROM with all your contacts, apps, etc.
6) When you want to go back to your original ROM that you had in the first place, follow steps 1 to 4 above to backup your new ROM
7) Then wipe your phone in xrecovery again, and go to backup/restore, choose restore, and choose the folder you backed up earlier
8) Now your phone will be back to the way it was before you wiped it in the first place.
9)now you can use these 2 backups, and easily switch between the two, by restoring a ROM when you need to
That is what I do and its very quick, and easy to do
PLEASE NOTE: THIS IS QUICKEST WHEN USING ROMS THAT WORK ON THE SAME BASEBAND! NOT ALL ROMS WORK ON THE SAME BASEBAND!
