T-Mobile USA has uncovered that the company will make the 4G tablet and this happen just after an announcement of Sprint 4G tablets. That’s mean you will be able to see a 4G tablet in the products portfolio of T-Mobile. 
We don’t know on what OS platform this 4G tablet will be running but there is some possibilities that it will come with Google Android 3.0 Honeycomb but nothing can be said by us with surety right now. T-Mobile Company only informed us about its intention of launching the 4G tablet while all other things like
features and specs sheet are kept under lock and key.
Here's the full statement:
“T-Mobile is working closely with the majority of our OEM partners to deliver 4G products by integrating HSPA+ into roadmaps in 2011 as the dominant global standard. Consumers will continue to see HSPA+ fuel future innovation in a variety of mobile consumer electronics from smartphones and tablets to emerging devices. T-Mobile will continue to be at the forefront of wireless innovation, delivering an aggressive 4G product lineup in 2011, including 4G tablets.”
It is really good that in 2011 we will have some wonderful tablet and laptop with amazing features. Acer Iconia will be launched on 15 January.
