These days I am grumpy with T-Mobile.  I have had a Blackberry Pearl 8100 for just one year.   This is my first 'smart phone' and it really has made me a more productive mom.  I really have enjoyed this thing.  Well, recently I have been noticing that lots of companies have been developing applications (a.k.a. 'apps') for the Blackberry (the middle age counterpart of the iPhone).  Two of my favorite programs (Evernote and Pandora) have released such apps.  I got so excited at the thought of streaming my custom radio stations and viewing my virtual notebook on my Blackberry.  (I know I am a geek).  But my enthusiasm came to a screeching halt when I realized that my Blackberry OS (operating system) needed to be updated and that T-Mobile NO longer provides updates for my model Blackberry (but they are upgrading other models).  Even though Blackberry has offered several software updates for my phone, T-Mobile won't customize it so it works with my cell phone plan.  So if I download the software from Blackberry instead of T-Mobile, features of my calling plan won't work.  Now remember, this is my 1 YEAR OLD Blackberry I am talking about.  I even found a T-Mobile customer service rep who was very competent and eager to please and spent 2 hours with me on the phone trying to help me find a 'work around', but with no luck.  So I am left with a hardware (the phone) that is perfectly functional, but because it has outdated software, it is fossilizing before my eyes.  I wouldn't think Blackberry would be too happy with T-Mobile.  They may lose a customer because the service provider won't let me update my OS.  I may just have to not act my age and get an iPhone.  What can I say, but "I want an app for that."
