Blackberry 5.0 software disappeared on my mac

[whereismytsquare]

So I was taking pictures the other day when my blackberry said it can't do it because there's not enough batter when i still had 2 and 1/2 bars left. i tried it again, took the picture, and when I viewed it the screen turned white. After an hour I took the battery out. It won't turn on. I connected it to my mac and said the disk could not be repaired. I had to reload the software and it only gave me options of 4.6.

I want my 5.0 software back everytime I click update software, my mac says it's all updated. What is going on? Why was a 5.0 available before and now it isn't?

oh yeah, i run on a t-mobile network so 5.0 was made available for my 8900
