My 9930 experience... Or lack there of.
Hey what's up my fellow bold touch stalkers. Just a few minutes here at work I was standing in a store and noticed a guy pulled out a bb. I took a closer look and noticed it was quite then. So I immediately go to him and ask if that was the 9900?? He did not want to answer me then said yes, it's the bold touch. This guy was SUPER DUPER reluctant to let me hold it. He put it in airplane mode so I wouldn't see the carrier name. I asked a slew of questions which he answered none of them. Sorry I don't have an exciting story about what I was able to do with the device, but this guy was very paranoid lol.
I can say all of what you heard about the 9900/30 is true. Feels super great and moves through/between apps nicely. I would assume typing is wonderful tho I did nothing else but hold it for 8seconds.
