I finally got my Sony Ericsson K750i to work with the Gmail for mobile application released last week. The first time I tried it, I couldn’t get the inbox to load.
It was puzzling as I could access the Internet using Opera Mini. I kept changing Internet settings and I still couldn’t go past the “loading” screen for the inbox. Just as frustration was threatening to boil over, I spotted the solution.
It turns out that you have to specify the Internet settings for Java applications in the K750i. If you’re using a Sony Ericsson with a Smart account, this might do the trick for you: Go to Settings then Connectivity then Settings for Java and pick Smart Internet. That solved the issue for me and I can now use Gmail on my phone.
The application is indeed faster and better to use. I have never been able to use the K750i’s default email program to connect to my Gmail account. I remember spending days trying to make it work a few months back, to no avail.
