When Motorola XOOM launched a couple of months ago, we were promised a hardware upgrade that will make it support 4G connectivity. All you had to do was send the device in and you got it back with the new connectivity standard. Well, this hasn’t yet happened to any XOOM owners and in the meantime Samsung’s Galaxy Tab 10.1 is about to debut on Verizon, in its 4G flavor.

There’s already an explanation for the Motorola tablet’s upgrade delay, as CEO Sanjay Jha said that the Nvidia Tegra 2 chipset is to blame. The strange thing is that Samsung Galaxy Tab 10.1 uses the same CPU and still it has 4G… Meanwhile, Nvidia is saying that there are no issues with Tegra and LTE compatibility.

I guess that there will be some angry XOOM owners who will envy the Galaxy Tab people who are cruising around at 4G speeds. As far as the blaming of Nvidia goes, that’s no way to treat a partner, Motorola!
