Two phones that will run Windows Mobile 5.0 have been the biggest buzz/rumors in the last couple of weeks - Windows Mobile-powered Treo 670 (that's right, first non-Palm based Treo!) and HTC Wizard.
HTC Wizard looks really slick - it is about the same size as i-mate JAM but has got WiFi, GSM/GPRS/EDGE, a slide out keyboard and will run Windows Mobile 5.0. Now, that is something I would trade my i-mate JAM for! If the price is right though... I only wish T-Mobile USA would offer something better than slow GPRS... say, EDGE...
BTW, found Rory's The two stupidest SmartPhone apps *ever* post - I agree those are very stupid apps I would never buy!
