Frow what I have read, gmail mobile doesnt work on the enV. I could be wrong, but I would say no to your question.
In regards to viewing it through the browser, I didnt have a hard viewing my gmail on the LG Vx9400. It actually looked good. So if you get the media package, you can view your gmail from the wap browser.
Hope this helps.
I am thinking about buying an LG enV. I have a gmail account and I would like to have Gmail Mobile on my phone. Does anyone know it the phone is java compatible, which it needs to be to get Gmail's application? If not, is anyone using Gmail through the WAP browser and is it a readable format?
