A tipster has sent mobile tech blog BriefMobile a screen capture of a spreadsheet entitled “End User Fulfillment Device Availability Report” allegedly showing release dates of several Android devices on Sprint. The screenshot shows that the report was last updated on July 22, 2011.

Although the source said that the dates shown on the spreadsheet are just estimated release dates, the list contains interesting Android devices.

For instance, the list mentions the Samsung Conquer D600, which has been rumored recently and whose arrival has been postponed to August 21, 2011.

The Kyocera KYC5120 Black also appears on the list, is set for release on September 9, 2011, and will replace the eco-friendly Samsung Intercept, which was release last summer. We’re guessing the Kyocera KYC5120 Black will also be an Android device, since the Samsung Intercept that it is replacing is also an Android device.

Another one is the Motorola Photon 4G (“Motorola MB855 Device Kit” on the spreadsheet), which has already been launched on Sprint and will start selling on July 28.

Another device on the list, the “Sprint M650 Handset Kit,” appears to be the Huawei M650 and has a target release date of October 30, 2011. It was recently spotted making its rounds through the Federal Communications Commission (FCC) and was seen to carry CDMA 800/850/1900, Wi-Fi, and Bluetooth internals.

Another mysterious device is from Motorola, with model name/number XT603. No other info about this device is available at the moment, except that it already received Wi-Fi certification. Sprint’s spreadsheet shows its scheduled release on October 2, 2011.

A tablet also appears on the list–the ZTE V55 tablet, with a target release date slated for first quarter of 2012. This is a mysterious device. We do not know anything about this yet. Since it’s coming to Sprint, support for 3G/4G connectivity is possible. We are hanging on to ZTE’s announcements at the Mobile World Congress this year regarding their intention to focus on Android and expanding to the United States, so we’re guessing this is going to be an Android tablet.

Take note that the Samsung Galaxy S II (or its name variant or rebrand) is not on the list. Could it be possible that the high and mighty Samsung Galaxy S II is bypassing only some carriers such as Sprint, contrary to our speculations that it may completely bypass the United States? A Samsung official did confirm, however, that the Samsung Galaxy S II will be reaching American shores, although the official kept his lips sealed about which carrier the handset is heading to.

That’s 6 Android devices coming to Sprint in the next few months. Are you doing your Christmas shopping early?
