Samsung Galaxy Tab is nothing more than a huge cell phone.

A video today showed that Samsung’s upcoming tablet Galaxy Tab, which boasts of a 7 inch screen, is nothing more than a huge cell phone. The Tab works as a full 3G phone.

The Galaxy Tab however, is no match to iPad, which has a 10 inches screen. Samsung is planning to release the Galaxy Tab in Germany on September 2. Samsung recently released a teaser video showing the features of the Galaxy Tab. It is expected that the Galaxy Tab will support Adobe Flash.

Blurring the line between phone and tablet even further, a video today shows that the seven inch Galaxy Tablet is also a huge cell phone.
Add two inches to that, and you have the Android-powered  Samsung Galaxy Tab which is somewhere between a phone and an iPad in size. And it works as a full 3G phone.
More realistic options include using a bluetooth headset or traditional earphone jack. It isn't certain if US carriers of the Samsung Galaxy Tab will require a voice plan (or even offer one) or if they will be sold like AT&T (T) sells its Apple (AAPL) iPads.
Speaking of iPad, the "Samsung Galaxy Tab" seems to be significantly smaller than the 10-inch screen iPad, though the resolution of the screens aren't that much different
