This is a limitation with Windows mobile and it's built in email client. I'm not sure if Flexmail or another 3rd party program allows you to change the "from" field but I haven't seen any way to specify that in the default app.

There are a lot of people using the Java GMAIL client but as with any java application you wont be alerted to any new messages and integration with the rest of the O/S is limited. Also, I dont think you can specify the "from" field in the java client either.
