I LOVE using my Treo 650 device and am very pleased with my decision to stick with it over the HTC Wizard due to its super functionality. Palm just released a ROM update for the GSM unlocked version yesterday (see the details in my Geek.com blurb) and I may have to perform it when I get back from Alaska later tonight. I haven’t seen many reports from people who have performed the update yet, but I like the listing that shows improved data performance.
I have been getting a super signal up here in Ketchikan, Alaska with my Treo and find it has the strongest signal of any device I have owned. The i-mate SP5m (HTC Tornado) also get an amazing signal, especially considering there is no external antenna on it.
