If I shelled out $300 for a new smartphone -- and maybe another $80 for Nokia's nifty add-on camera grip/battery pack -- I would be livid hearing about more advanced models coming very soon. Nokia shares were losing 2.14% to $4.12 and Microsoft shares were down 0.28%% to $35.41 at 10:41 a.m. in New York. Companies are constantly working to improve their current products. That's a good thing. It keeps the industry going. But, at some point, the buying public will push back. Something has to give. Apple takes a different approach, improving their iPhones every year or so not every month. That schedule seems to work very well for them. T-Mobile ( TMUS) is taking the opposite approach to what has become never-ending consumer smartphone envy. For an additional $10/month, you can sign-up for T-Mobile's "Jump!" program. It allows T-Mobile subscribers to switch/upgrade their smartphone (if it's not damaged) twice a year. T-Mobile's solution looks like a win-win situation for all sides -- keeping innovation advancing at a pace as well as offering a way for consumers to take advantage of it all without going broke. --Written by Gary Krakow in New York. >To submit a news tip, send an email to: email@example.com.
