Dude,
You're not going crazy. I'm having the same problem. I installed an imap Gmail account and then deleted it to try the Sprint Mobile E-mail setup for Gmail (because it is push mail) and the Sprint Mobile E-mail named it Gmail1, presumably because the imap account never really deleted. I am going nuts, because now I can't get the Sprint Mobile Email account to register properly with the server. I have looked in the registry, but I am finding nothing. I will let you know if I figure it out.
Cheers,
DJ
