According the sticky post in the AT&T S2 section of this forum, "25 reasons to consider the AT&T Galaxy S2":
It's Not Bloated
Some may love the pre-installed apps. Others may want to delete them. Carriers often prevent you from removing pre-installed "bloatware" without breaking your warranty. Samsung is allowing users to uninstall bloatware. Tap Home > Menu > Settings> Applications > Manage Applications to delete apps.
Is that really possible? I found no way of doing that with my un-rooted T-Mobile S2. I've never heard of an Android phone that you could do that with.
I was also surprised to see that the screen on the AT&T version is only 4.2", not 4.5", and that it used a slower CPU.
Getting rid of bloatware without rooting would be great!
