14 DAY TRIAL // For some obscure reason, Amazon chose not to say which version of the Android operating system was installed on the Kindle Fire HD, the new tablet, or should we say tablets.
The original kindle Fire ran a modified version of Android 2.3 Gingerbread, but it had a completely modified user interface.
We assumed Amazon did the same with 4.0 Ice Cream Sandwich this time, but for all we knew it could have chosen Android 3.0 instead. Naturally, we also hoped Android 4.1 Jelly Bean would be featured.
Nevertheless, assuming the report on Slashgear is accurate, the Amazon Kindle Fire HD do, indeed, run Ice Cream Sandwich, one that integrates an ad mechanism which, when the tablet goes into lock screen, shows an Amazon ad, complete with special offers from the store.
