I am testing the zoho app on iphones and would like to know if it can do the following. firstly i actually can't get onto the free trial database i have produced for testing. a message on my iphone says i don't have an account. i obviously created one. the second question is.. can i tap a phone number in the app on the mobile and trigger a call. thirdly will i be able to link the database to the iphone calendar?
