NEW YORK ( TheStreet) - T-Mobile USA ( TMUS) is holding a big event today in New York City. The company hasn't leaked too many details in advance so predicting what will be announced is somewhat difficult. The last time T-Mobile came here was back in March, when CEO John Legere very bluntly announced that his company was going to "Stop The Bull****" when it came to cellular phone service plan pricing, as the company announced its new "no contract" pricing plans. At that event, Legere said that if you bring your business to T-Mobile "you've signed your last contract". So far, it doesn't look like customers have responded in droves to that offer. T-Mobile is still in fourth place behind carriers Verizon ( VZ), AT&T ( T) and Sprint ( S). T-Mobile may say something positive to say about how well its new initiatives are actually performing. Since the company's invitation hinted today's announcement would be its "boldest moves yet," there may be some tweaking of those payment plans to make them even more attractive to potential customers. T-Mobile shares were advancing 0.5% to $24.21 in early Wednesday trading. There could also be some boasting about handset sales. Now that T-Mobile has finally joined the Apple ( AAPL) iPhone sellers club, it have some positive things to say about how that handset has been affecting its bottom line. We also hear about some of the new smartphones T-Mobile might have coming soon. There have been hints Sony's ( SNE) Xperia Z Android phone and Nokia's ( NOK) Lumia 925 running on the Windows Phone OS might soon become available for purchase, perhaps as soon as next week. Now that the with MetroPCS has been completed, we may very well hear more about that division's newest addition - a Samsung Galaxy S 4 model of their own - announced just a few days ago. It's still all speculation at this point, but, we'll know a lot more very, very soon. --Written by Gary Krakow in New York. >To submit a news tip, send an email to: email@example.com.
