yes you can use any baseband on any rom or version you liked, it dont matter!have no fear your boy is here, i have everything you ever need on *********** under the name fbiguido... but for the base its the last link on this page baseband.zip - *********** download free under my name as baseband.03 and .04 both are update.zip method to load...
have fun and dont worry i have everything backed up and if you need help. feel free to pm me and ask! edit baseband.03 is the 2.1 and bandband.04 is the first froyo and baseband1.43.01p is lastest pete's all in one 2nd froyo update
so .03 is the old one your looking for and baseband1.43.01p is the lastest one if you want to go back
So I can just download the zip and update it in the startup screen even if I am going backwards?
Can I use the 2.1 baseband with 2.2 froyo? I had the best service before I rooted my phone which was in 2.1.
but you have to re flash the baseband you want everytime you want to change it, in SPRecovery by holding the x button and powering on ur phone and hitting the install button... and just b'cuz you go back to an old nandroid backup of something that had a different baseband it will stay the most recent one til you reflash the baseband.. you can check for yourself by hitting setting, about phone and look for baseband version and it will tell you which one your currently on
