If you are the type to look at the bright side of things, then you might see this next bit of news as just further proof that HTC doesn't want their earlier work to go to waste... Otherwise, you might be frustrated to find out that there is a new update set to roll out soon for the HTC Thunderbolt, but it still does not include Ice Cream Sandwich. This new update is basically the same as one that was leaked a few weeks ago. Still, it has some bug fixes and feature enhancements, so it is definitely better than nothing.
The newest update is version 2.11.605.19 710RD, and it will supposedly be rolling out fairly soon. The update primarily fixes issues with data connectivity, Yahoo! Mail, and Mobile Hotspot amongst a few other things.
