Whether you're using an iPhone, Blackberry or any other smart phone, you can chat with website visitors just by downloading an IM client on your phone. eBuddy is our personal favorite and it works well on iPhone.

Zopim puts your IM on steroids - do you know that you can list shortcuts, set name of visitors, send shortcuts etc while replying to customers on IM? Zopim lets you do all that with a funky list of commands

Need to switch to IM while using the Dashboard or vice versa? Existing chats are automatically synced so you can continue the conversation, without disrupting the chats with your customers.
