After updating basebands and flashing several ROMs I had noticed degradation in both reception and battery life. Since I was OC'd I chalked up my poorer battery life as a side effect to my love for speed. The new basebands were probably necessary for Froyo compatibility, but since my knowledge is limited in that area, I can't be sure. Either way, my reception suffered. During one of the times my signal dropped, I decided to look into my network settings and noticed under Mobile Network Settings/System select, that my phone was set to Automatic instead of Home only. After selecting Home only, my reception improved as well as my battery life. The better battery life I attribute to the phone not looking for a signal as often and am so much happier now that I've found this. Just thought I post my experience and see if anyone else has had similar results.
