i don't remember how, but i rigged one of my old phones to automatically switch to sprint when i was in my underground garage because i wouldn't get reception on verizon but I would on sprint.
PRL on my Galaxy Nexus is 15098.
PRL on the three LG Envy 3's is 52642. These three phones are all up to the latest version using the *228.
From what I have read you can not update 4g phones using *228. To do this it is necessary to pull battery and sim card and that should update it if necessary.
