Google has been active these days in the mobile phone market after the introduction of its Android Platform. The recent addition to this is the offline mail browsing feature which is now extended to work with iPhones. iPhone 3G and Android HTML 5 can now access this feature easily, giving users an offline browsing experience. This will enable users to download the mail service when the internet facility is available, and then review the mails later on by the offline mail-checking system. Although, this system is already available for PCs, this is now extended for iPhones too.
Google gears is used for the synchronization of your mail to the web servers. As long as you’re connected to the network, the cache is synchronized with Gmail’s servers. When you lose your connection, Gmail automatically switches to offline mode, and uses the data stored on your computer’s hard drive instead of the information sent across the network.
You can read messages, star and label them, and do all of the things you’re used to doing while reading your webmail online, with the same ease. The messages you send while offline will be placed in your outbox and automatically sent the next time Gmail detects a connection. And if you’re on an unreliable or slow connection (like when you’re “borrowing” your neighbor’s wireless), you can choose to use “flaky connection mode,” which is somewhere in between: it uses the local cache as if you were disconnected, but still synchronizes your mail with the server in the background.

But for iPhones, this is not completely the same. For mobile devices such as iPhones, the Gmail is dependent on HTML 5’s Appcache, which means this requires no additional software downloads.
