*228 option 1 will program the MDN, MIN and Home SID into the phone, download the latest PRL, and set the lock code to the last 4 digits of the MDN.
It will never download the PRL for me using option one. Many others have had the same experience. The only way for me to ever download PRL is to use option 2 (or *22891). It must be a regional thing if some are getting the PRL updates via *22890 or manually using option one.
I had that trouble, too, and reflashed 4.0 to take care of it. Now that I know the info written in this thread, it might just be time to put 4.2 back on the phone. BTW, I put a direct dial *22891 icon on my desktop and it works wonderfully.
