I saw this a week or so ago, but it popped up again on Harolds blog.  This is the deal, you sign up for new service with T-Mobile and get the MDA phone for $79, the SDA phone for free.  I have gathered some info on both phones and posted it below.  The cNet review of the MDA phone was not favorable – but if you read the user review several of the them comment that cNet is crazy.  The user reviews of the MDA came out to 8+ while cNet gave it something like 6.7.

MDA phone is a PDA essentially with a QWERTY keyboard, it also comes with mobile Office.  It’s kind of bulky, but if you have a crackberry or PDA now, it’s about the same size.  The SDA is smaller and only has a number pad, so if you are into IM, the MDA would likely be a better choice. 

I had T-Mobile before I went back to Verizon and I never had any problems with their service (my zip is 92373) or CS.  I am seriously considering ditching my Verizon phone for the SDA and then selling my Dell x50v that I never carry or use.  My son has been asking for his own phone so he could have my Verizon phone – not that he needs it but peer pressure starts early. 

More info below on both of the phones. 


BTW I grabbed all this info and created a side-by-side comparison in OneNote, notice the pasted from links that OneNote auto creates.  It would have been great if I could have posted directly from OneNote and kept the formatting.
