Just received an email from Handspring which announced that Cingular service available in my area. Checking the site I saw that for some foolish reason they are not offering an unlimited data plan. You can only pay more (24.99) to get get 10 MB/month. On the same page, you can see that Sprint is clearly charging $15 for unlimited data and about $5 more for the same level of voice minutes.
There are other differences in service, like Cingular’s rollover minutes and Sprints desire to charge $.50/min when you roam off their network…
Hopefully AT&T or T-Mobile will have a good deal on this by the time Portability hits.
