Looking for an upgrade to Windows Phone 7.8 for your Nokia Lumia 710 on T-Mobile’s network? If so, we are said to report that you are apparently T-Mobile is skipping the upgrade altogether.

The word comes directly from a 710 owner that decided to contact Nokia directly about whether or not his T-Mobile handset was getting the upgrade to 7.8 or not. Here’s what Nokia had to say:

“In response to your concern, we understand that you want to confirm if the Windows Phone 7.8 will be available for Nokia Lumia 710 from T-Mobile. We are sorry to inform you that there are a small number of operators that have chosen not to offer the update to their users. It is important to recognize that this decision was made solely by the operator and these include the T-Mobile network in the United States.”

Basically, it wasn’t Nokia’s decision, but a carrier one. For the record, this probably also applies to the T-Mobile HTC Radar as well.

The good news is that the technically inclined folks out there aren’t left completely in the dark. It is completely possible to manually install Windows Phone 7.8 using CAB files. Certainly better that nothing.

What do you think of T-Mobile’s decision? Are you still clinging to the Lumia 710, if will you ditch the phone as soon as you can to move to Windows Phone 8 or perhaps a completely different platform? Let us know in the comments below.
