Has anyone tried disabling the ultrasn0w mobile substrate plugin through sbsettings? I'm on 2.x.... baseband and disabled it, and my reception bars still work. So for anyone who is just preserving the 1.59.00 baseband but doesn't need an unlock, this might remove the unwanted effects of ultrasn0w.
Good idea.
If anyone still has VV and MMS problems try this above and see if it fixes things?
