how do I know which PRL is on the phone right now?
also, lets say I flash this, if I do an update prl from settings, will that just take it back to stock or rather released version? or once I do this, it'll break that feature.
No need for a hands free activation, you can do as you mentioned and just go into your update PRL from Settings and get it done that way to get back to your 'stock' PRL.
From my experience, disabling data first will cause this to stick more times than not.
As another guy said, use Google to search for the anycut apk and you can create a shortcut that way. It's listed as 'PRL Write' within the app. Once you do this, you can just click that shortcut, hit the button and the phone will reboot. Not a big time saver, but one nonetheless depending on how often you're planning on using this.
If you use the 00001.prl (VZW only) it will show up as '1' in 'About Phone'. The preceeding 0's are omitted for some reason.
For me personally it's the only one I use as Sprint doesn't have a roaming agreement with VZW in Chicago, so if I have a bad signal, this is my only choice.
For those of you just changing a PRL to enable 3G data when you roam, let's say naturally, you probably won't need to revert back at all. In that case, just freeze System Update so Sprint doesn't roll you back after a day or two.
