Upgrading - Backup(ing)

[goralpm]

Hi.
I will be upgrading my ROM in XDA Exec (actually 1.30.107 WWE - original one from O2)
First, what ROM it will be nice, best?
Second, I have some software's installed on my device. Can I backup them and next just restore in new ROM?
I have CoPilot I relay don't want lousing licence key...
It will be working with backup?
Thanks

And just forgot:
Can I beck to my old ROM?

1. There is no "best" ROM, the best way is to test severals till you get the perfect for your needs, however I can recomment Tomal ROM´s
2.- As far as I know there is no way to backup apps, but you can easyly re install them on your new ROM, you won´t loose any license key

Good luck,
