T-Mobile (News - Alert) brought out its Test Drive recently in a bid to show off their impressive phone data speeds, but what they got instead was controversy from their users.

T-Mobile's Test Drive Web site serves as a kind of head-to-head comparison, showing off the differences in speeds between the various phones T-Mobile offers and their competitor Verizon's iPhone (News - Alert) 4S offering. One comparison launched between a Samsung Galaxy S II running on T-Mobile's network and an iPhone 4S running on Verizon showed the two phones streaming Netflix content.

T-Mobile ran a stopwatch over the two and showed that not only did the T-Mobile phone load Netflix faster, but it could jump to a different part of the movie shown, while Sprint's (News - Alert) phone was still buffering the initial launch.

T-Mobile then illustrated the differences in pricing between T-Mobile and Verizon, with other videos showing other phones taking on the iPhone 4S to download apps and photos.

It was at this point that some cried foul, as the iPhone 4S was a standard opponent in all three direct trials. The problem here is that the iPhone 4S is not technically a 4G device – rather an HSPA+ machine. And though that by itself has engendered some controversy as to whether or not HSPA+ is the equivalent of 4G, it was eventually decided by the International Telecommunications Union that HSPA+ is a type of 4G, as is WiMAX (News - Alert) and LTE.

The issue now is whether or not it's a fair test for T-Mobile to put a 4G LTE device up against an TSPA+ device.

T-Mobile has been having a rough time lately, with a failed merger with AT&T and incurring some FCC (News - Alert) fines, so it's not so much of a surprise to see T-Mobile looking to shake up its image. That's why these days the commercials’ Carly has stopped wearing the pink dress, and instead busted out the pink-trimmed leathers and the souped-up Ducati, tearing down streets like she's got the greatest health insurance plan on Earth.

Still, T-Mobile's got a good marketing plan in its test drive ads. While speed claims may be questionable, the pricing is hard to quibble. And on pricing, T-Mobile does a good job of staying competitive. That’s going to get a lot of people in the door.

The economy is still floundering at best, and these days, people want value. If a business can prove it can provide value, it's going to get a lot of interested parties looking to jump ship from their current providers or looking for their first phone.
