There is much buzz about the Blackberry 8320 and for Treo users like me it's probably a welcome replacement.
If you're a T-mobile customer and have an extensive history of problems (they've documented) make sure to ask for extra good customer pricing. I just got it for $249 based on a long track record of device issues.
Still I think T-mobile's phone / data plan combos plus the unlimited hotspot access plan is the best around.
OK I actually got another Treo, same static. Then got T-mobile reps to informally admit they aren't supporting the Treo.
Anyway I saw on the net that the Blackberry Curve is coming to T-mobile probably sometime in September. Given my obscure phone requirements (email, good PDA, camera, speakerphone etc) I am STOKED. I tried the T-mobile Dash at one point, and again yesterday with Mobile 6, and it just didn't cut it. I thought I'd share the good news.
