"It is possible that the update will see delays depending on each network, but it should be available for all users in the end." The Gingerbread update for Desire Z arrives at the same time with the OS upgrade HTC is readying for the original Desire smartphone. Recently, the handset vendor announced that HTC Desire owners out there should be receiving the Android 2.3 Gingerbread OS before the end of July, without the HTC Sense UI loaded on top. Earlier this year, the company started upgrading the Desire HD to Gingerbread.
