In an interview with Fierce Wireless, an executive from T-Mobile let it be known that there will be follow-up devices to the G1 and that they will be out this year. Neville Ray, T-Mobile's Senior VP for Engineering and Operations said that his company will be offering more G series phones along with other products, like a data card, in the weeks and months ahead. The G1, currently offered in the U.S. exclusively on T-Mobile USA, is the World's first cellphone running on Google's open source Android OS. There have been many false starts in the race to become the second Android phone
, but it appears that T-Mobile plans on expanding the line in 2009. The G1 is a touchscreen model that also uses a trackball. It has a physical QWERTY keyboard which will be supplemented with a virtual QWERTY as part of the Cupcake upgrade for the device, which is expected to be released soon.
