| | Re: Will install of .480 prevent my T-Mobile from receing OTA updates in future?
If T-mobile operates anything like AT&T, then installing an OS unrecognized by T-Mobile will prevent the OTA update check from working (and this may not be a carrier issue as much as it's just the way things work). You can always manually install any future OS updates, however, just as you are contemplating doing now with 480.
