HTC Merge users on US Cellular, your day has come. Forget about Froyo, aka Android 2.2, and zoom straight to the latest version of Android available for non-Nexus phones - 2.3.4 "Gingerbread" (HTC version 3.10.573.1 to be exact - the image below taken from the update guide is outdated).
The update will need to be applied on a computer using HTC Sync and will wipe your device clean of emails, contacts, calendars, apps, bookmarks, and any other personalization - it'll basically be back to stock. Pictures, movies, music, and everything on your SD card should remain intact, but you'll have to set up your Merge from scratch once the update has been completed. Sorry, no OTA update will be provided - you *have* to use a computer.
As for what the updated OS brings to the table, US Cellular provided the following list:
- Improved Power Management
Actively manage your device's performance and achieve the best possible battery life with improved power management features.
- User Interface Refinements
Enjoy a refined user interface that includes updated menus and settings that allow you to navigate your device with more speed and simplicity.
- More Control Over Applications
- Check and manage application activity quickly with new shortcuts and easy-to-read displays of running apps and the memory they are consuming.
- Improved Text Interface
Input and edit your text faster and more intuitively than ever with the redesigned and optimized
- One-Touch Word Selection and Copy/Paste
The improved text interface allows you to copy numbers, addresses, URLs and much more, then paste them anywhere quickly and easily.
Surely, the list is way too small - there are many other improvements US Cellular and HTC didn't address there.
