I remembered I was on a Europe trip and needed to check my Gmail once in a while using my O2 XDA IIi PDA. The PDA screen is too small to be using the normal Gmail web interface. So I searched around and found Gmail Lite. It’s open source, and to be honest, it’s quite problematic. Although Gmail is out of beta but it is always in constant revision. So there will be updates here and there and resulting Gmail Lite unable to use until the author or someone fix it to be compatible. Other than that, some people may not be comfortable in logging in to their Gmail account from a non official Gmail webpage.
As time goes by, Google has made tremendous update by allowing all devices ranging from devices as old as Nokia running Symbian to as new as iPhone 4S to access your Gmail account. There are a few methods on how to check your Gmail from your mobile depending on what type of device you are using. If you are using an old mobile that runs on Symbian such as the S60, you will need to visit simple and light version of Gmail at http://m.gmail.com from your mobile’s browser. In fact this method works for all mobile devices including the newer ones if you do not wish to install an app for it.
As for devices running on iOS such as iPad, iPhone and iPod Touch, you can download and install the free Gmail app developed by Google themselves from the iTunes App Store. For mobile devices running on Android, there is a Gmail app as well which can be installed from Google Play. The good thing about installing a Gmail app is to have push notifications so that you will be notified when a new email arrives in your inbox rather than manually visiting the Gmail mobile page to check if there is a new email.
Alternatively, Gmail also supports IMAP and POP where you can configure the pre-installed email client program on your mobile devices to sync with Gmail. You must first sign in to your Gmail account to enable the IMAP or POP from the settings. Here are the official instructions for enabling and setting up IMAP and POP for your Gmail account.
