As early as next week, January 9th to be exact, T-Mobile could be launching a truly unlimited 4G nationwide data package with their Monthly4G plan.  According to Engadget, a leaked product image shows T-Mobile is getting ready to replace the 5GB throttled data plan with what reads to be a truly unlimited data package for only $70 per month.  The $70 price per month for unlimited 4G data should also include unlimited talk and text.  All of this comes with a no-contract offering that’s been integrated into T-Mobile since the acquisition of MetroPCS, which according to TMoNews makes the whole thing a win – win scenario for mobile customers.  T-Mobile’s unlimited nationwide 4G product goes by the name of Monthly4G.  Now the only question is, when will you jump ship to T-Mobile?
