I happen to have a couple of friends who work for Sprint and after much cajoling (and some bribery. Seriously... it's going to cost me some drinks) one of them agreed to answer some questions about the Pre. His terms are quite logical. He won't answer anything he is strictly forbidden to reveal, he will not answer anything that could personally identify him to the company and he won't answer questions regarding the App catalog since technically it doesn't exist yet.
Rather than being stingy and asking it all myself, I decided to open it up to you guys. Go ahead and ask here what you'd like to see answered and I will submit the questions to him either tonight or tomorrow. He'll choose which ones he can answer and I'll post it all right back here.
So what are you waiting for? Ask!!!
