iPhone does have activesynch, so does android.
activesync | Android Central
Apple - iPhone - iPhone in Business
Desktop Manager is not a solution. Who wants to go on business travel and leave a computer running to ensure they keep mail, contacts, cal synched up? better yet, if they only use a laptop and that laptop travels with them? That's a hard sell when two other phones do it without a desktop piece or paying for another service on top of email such as hosted BES. --- This is almost verbatim what two clients have already said to me, because i suggested a hosted BES solution.
BB's are my preferred smart phone solution but now doing consulting I see them through small business owners eyes and realize they are limited in what they can do when you don't have a BES.
I was hoping to find something other than astrasynch but haven't been able too.
