The HTML5 version of the mobile Gmail app hasn't exactly been friendly towards non-American users to date; English (and indeed what Google calls "U.S. English") was the only language in which it was available. Now, however, Google's addressed the problem in a big way.
Today, there are 44 new languages on the figurative table, and that should account for the vast majority of people who are likely to own a smartphone. An Android device or anything running a recent version of iOS, in fact.
So here's the full list: Arabic, Bulgarian, Catalan, Chinese (Traditional and Simplified), Croatian, Czech, Danish, Dutch, English (UK and American), Estonian, Filipino, Finnish, French, German, Greek, Hebrew, Hindi, Hungarian, Icelandic, Indonesian, Italian, Japanese, Korean, Latvian, Lithuanian, Malay, Norwegian (Bokmal), Polish, Portuguese (for both Portugal and Brazil), Romanian, Russian, Serbian, Slovak, Slovenian, Spanish (for both Spain and South America), Swedish, Thai, Turkish, Ukranian, Urdu and Vietnamese.
A post on the Official Google Blog also explained, "If your phone's default language is one of those listed, go to gmail.com in your phone's browser and the new interface will appear in your language automatically. . . . You'll get a bunch of new goodies including offline support, smart links (titles will appear in links for Google Maps, YouTube and Google Docs), the ability to add and remove labels, layout improvements and more - in addition to the existing features like starring, better threaded conversations and search."
This development should help Google win quite a few more fans in the international community.
