Fortunately, it appears that the case is so as unlocked versions of the Palm Pre 2 are also starting to see the official webOS 2.1 update. With it, owners can expect to find two specific new features that will come to be appreciated by anyone – these include Exhibition Mode and voice dialing.
First and foremost, the new Exhibition Mode is supported with native apps on the device like the time, photos, and agenda apps. However, it can also be enabled by certain third-party applications as well. Secondly, voice dialing surely took some time to come around, but it’s now finally accessed by simply holding down the volume key or holding on the phone dial pad. Furthermore, there are also some other bug fixes along for the ride to smooth out some security issues with the platform.
So if you’re sporting an unlocked Palm Pre 2, you can essentially get the update by running the update app on the handset.
