Even though the Android has changed the way things work in the push-mail. Yet more choices or competition generally bring out the best. I recently came across this offer which would be only for India as this carrier does not operate outside India. It would be interested to know what more they offer besides syncing contacts, calendar, tasks and notes etc. apart from the Push-mail. It is claimed that they support almost all popular devices including blackberry and android.

The service is available for Rs. 80/ per month. A good option if BSNL is your carrier and you are struck with that Shylock Blackberry.
