Did you guys try the Mobile Email software? It's preloaded on the phone under tools on the go and is free if you have the Verizon Premium plan. This program allows you to check email without having to use the web browser. It has Yahoo, Windows Live, AOL, Verizon.net and an option for pop 3 accounts too.
I've had the phone for 3 weeks now and yesterday configured the Mobile Email Software. The feature I really like about it is that it will give an audible indicator when a new email has arrived to one of the configured accounts, similar to the Blackberry Internet Service.
At the same time, you can close the MES to stop receiving alerts, another added bonus. So far I really like the MES on the Voyager.
