This has probably been asked somewhere in these 200+ posts but I don't know how to search inside threads.
I have v4.5.0.52 on my Curve and I just noticed T-Mobile released 4.5.0.81 (like this post). The common question -
Is there any difference between 52 and 81 that should make me want to upgrade? Other than this is an official Tmo release.
Thanks!!!!
