Hello there!
I got an iPhone 3G on 4.2.1 , BB 06.15.00 (iPad baseband) using unlock and I would say it is as slow as death...
Sms and other apps crashes all the time
so I was thinking about downgrading to 3.3.2 and port android.
Would you suggest me to do so?
Will it be fully compatible, or am I going to have problems? Also, what about the unlock?
Also, some months back I wasnt able to downgrade from 4.2.1 without the SHSH files, which I didn't have, though as I've lately read this can be done now.
Is that true?

thanks in advance
