I???ve tried downloading the updates. yet all that happens is my phone is usable for hoursssssssssss. a message came up saying file is corrupted. i tried again and all i have is a phone i cant use. the updates said 10 ??? 15 minutes to complete buts its been more like 10 ??? 15 hours. why is this happening? is there a site to download the update from other than the phone?
