I am using bharatberry since few days,, and it work great. I dont think security is an issue.. what security you are talking. Blackberry is pulling emails from our/your server through pop/imap . In most cases password from blackberry server travels unencrypted, our emails are not encrypted and available without any decryption.
Contacts / calander / task and notes are synced by bharatberry sync client just in 2 minutes , i have 700 contacts. Its free till feb and after that they plan to charge 1$ (50/- ) per month. which is nothing , its definitely worth trying.
I will support Bhartberry even if its less secure (which some people here seems to think so without trying and sharing their experience about security). I think its unfair
Blackberry is great and there is no doubt about it, but i am loving bharatberry and now bharatberry software is available on Nokia phones too.
