AndroidAndMe is reporting that an Android 2.3.4 update is set to arrive June 30 with a number of notable additions, including Skype video functionality, Google Talk video chat, and the Amazon Appstore. What's more, the update will also include Verizon Phone Finder, Download Manager, and a newer version (2.1) of HTC's Sense UI.
Looking at the purported update sheet, I don't see much in the way of bug fixes or performance enhancements. Indeed, one such feature that many Thunderbolt owners are hoping to see is a fix for the random rebooting issue. That alone would be worth a maintenance release. Still, though, I can't imagine users not wanting to be first in line for Skype video calling on an Android phone.
