so as long as your on bootloader 30.01 you can use the 2.1 sbf even though I already used the 2.2 sbf that didn't change my bootloader?
If you use the 2.2 sbf, and your bootloader still says 30.01... pretty sure you still use 2.1 .sbf. :S
I can confirm.. I'm still on 2.1. Next time I'm gonna .sbf with 2.2 and I'll letcha know... but that's my understanding at least.
