Just a few days back, T-Mobile announced that – along with its other holiday deals – it would be kicking off a “massive” Cyber Monday deal (or deals) tomorrow.  The carrier stated that it will announce the offer tonight at 8pm Pacific/11pm Eastern.

“And there’s more holiday goodness to come. Next up, Cyber Monday’s right around the corner. Watch for a message from us telling you all about T-Mobile’s very special Cyber Monday offer this Sunday at 8:00 p.m. PST – and then get your browsers warmed up for 12:01 a.m. PST on Cyber Monday, December 1st.”

We’ve still not heard any specifics on what this offer entails, but the announcement and offer should show up on the T-Mobile holiday deals page later tonight.

Update: T-Mobile got in touch to inform us that the scheduled time of the offers has been pushed back by two hours. This means the offers won’t go live until 2:01 Pacific/5:01 Eastern, with an announcement due at 11pm Eastern.
