One, he's not trolling. During the last major outage others reported this and.found their PRLs changed from 15098 to 62452 or something similar. One guy did a battery pull and facfory reset to try to stop the update but his phone kept autodialing the number.
Two, that number is not preloaded in your contacts. If i factory reset my phone and don't log back into my account during set up, then I have no contacts period.
Three, *22899 is a shortcut way of callinv *228 then option 2. I used it all the time to update the PRL on my 3G phones.
I don't mean to sound harsh, but it's ridiculous to accuss someone of trolling when yku obviously don't know all the facts. Doesn't that make YOU the troll, instead?
And I honestly don't know if it was known to brick the older 4G phones as this is my first one, but I can assure you that by setting *22899 as a contact and dialing it thats way will not only update your PRL on the GNex, but will not brick this phone.
