T-Mobile has announced on their support blog that the Windows Phone 8 software update for the HTC 8X has been delayed on their network.
The carrier said:
I know you were eagerly anticipating a new software update today and I wanted to give you a status update. In order to ensure the best possible experience with your device, we have temporarily delayed the release of the update to perform a few tweaks. Weâ€™re working hard to ensure that we get the update to you as quickly as possible.
Pocketnow notes that a delay such as this usually means some problem was detected, so it is probably best that it be fully fixed before the roll-out recommences. Hopefully it will not be an issue which also affect other OEMs also.
