One of the best mobile to have ever been bought by me. It does not have 3G and GPS but has all the other features and they work so much seamlessly that am not even switching it off ever now.
The service provided by BSNL in Chennai or esp in south is exemplary. There could be some small or minor hiccups when you start roaming in maharashtra, Calcutta or Orissa. (These were some states I recenlty visited) and the service was not up to the mark.
Did have the people in BSNL to look into it and the issue is being resolved or has been resolved. Have dumped my N80 (Nokia’s first 3G phone) for this and not regretting it now. Email configuration on BSNL blackberry servers are a breeze too.
In short would strongly recommend anybody who needs all his emails to be available but not on the normal and broader blacberry models but on a small form factor and that too a flip one.
