I'm current use Treo 600 with T-Mobile.I love Treo and I must stay on palm base.

I'm planning use Unlimited Data Connect for $45 month. I'm thinking about to buy Treo 650 Cingular service. I know Cingular provide email account. How fast Cingular email receive? Is that email fast receive like blackberry? Does it include unlimited text message? I maybe can try it for 30 days trail.
