Google have taken another step towards being omnipotent with the release of their new product, GMail for mobile.
It is an excellent little Java app for your Java-enabled mobile phone. It doesn't just allow you to look at your email from your phone, it also supports viewing images and even PDFs.
Sure, it isn't exactly easy to compose and read emails on a 5 cm, 320x240 resolution screen using a alphanumeric keypad, but for those times when you need to keep an eye on your email it works really well.
The only downside is the stupidly expensive GPRS data rates that all the mobile carriers have.
