hey this might be a noobish question, but i wanna update my phone to FroYo 3.70.651.1 without downloading a new rom (i am rooted) is there a way to do this without getting a new rom? and if so where can i find it? i searched but all i can find are roms with the 3.70. im guessing i can just download 3.70 and flash it but not for sure and i cant find it to download it.

thanks for any help!
