Don't you have to have a Citrix client in order to connect? Since the iPhone currently doesn't allow 3rd-party software (officially), does such a client even exist?
There is a Java app version of the connection software , it isn't a full citrix client , we use it on non controlled machines to log in ( ie web cafe machines ) not sure if that would work on the i Phone . Haven't got the opportunity yet as the iphone hasn't been released here yet. I might get a check on whether the iPod Touch can do it , as far as I know the web functionality should be the same on both, no ?
Anyway the point I'm trying to make really here is that Apple have probably looked at the whole exchange syncing thing and analysed it from the point of view of security , thinking along the lines of " you only need to sync to view offline , it's a technical difficulty and the permutations to support are too many, is it not better to ensure High availability ( unlimited data plans ) to remove the need for offline viewing , then provide one solution for secure connectivity with the server , supporting not just mail , but all apps available "
That is of course , back to my mac on OSX and something akin to citrix secure onto a windows network or VNC on a 'nix.
Maybe I'm just reading too much into the iPhone and what it is , but I feel it in my bones , it is heading towards the mobile PC , and the relationship between that mobile PC and the Home PC / Server is going to be a strong one .
If anyone does get an opportunity , Id love to see if the Safari on iPhone can make a Citrix connection ,
