i used the sbf to go to 2.1, then i rooted and installed sprecovery does this change anything when using nandroid? or can i still flash any nandroid rom? do they have to be 2.1 roms? is it any different than just flashing a rom on 2.0.1? also, is it a bad idea to use the sbf to go to 2.1 like i did? its running really nice, but would it be a good idea to go back to 2.0.1, the do a nandroid to bb 2.1? thanks edit: really what my question is- can i go flash-happy on this flashing nandroids. the main one i want to konw about is when the senseui rom comes out it will probably be a nandroid, will that nandroid play nicely with the 2.1 files that were installed when i flahsed with the sbf?
