Same here. We are now looking into other solutions. I need to upgrade my Cisco firewall and use in-house push technology. If you guys use an unlimited data plan already, see if you can forward your email to an IMAP or POP3 account such as Gmail. Then retrieve your emails on your phone by using this shadow account. For calendar, you can load Google Sync on your desktop. Either way, you can work around for "free". It's a pain in the butt but if I remember well, Xpress Mail is a free tool, right? You pay for unlimited but Xpress Mail is available for free. So AT&T could care less about all of this.

I actually have been looking at their iPhones and IPSec via Cisco to get emails from work. I read some good stuff on how UCLA get it working for their staff and students. Yeahy, yeah, I'm still going to give my money to AT&T but it's my fault for trusting them with Xpress Mail in the first place knowing it was a cheap product.
