Are you sure that this O/S update wouldn't fry my card on my T-Mobile BB Pearl 8100? From reading the posts some users said it was okay, so I just installed it ahead but just to make sure is it still safe? What would happen? The main post said that in a week it would fry out. Does it explode or fry my battery or anything? I just want to make sure that this is safe for my BB that is all.
