Apple's iPhone drew criticism when first released because of tepid enterprise business support. Small businesses felt the pain of iPhone envy more sharply than their enterprise counterparts because of the high up front cost of the first iPhone and the back-end support requirements for high-end e-mail and communication servers.

But the second generation of iPhones, the new 3G version, answers almost all these issues.

Costs are down to below what many people pay for other smart phones.

Integration to existing e-mail servers is faster and easier. Yet those back-end servers still require heavy investment up front and technical support later, especially when loading up a new Microsoft Exchange 2007 server.

Let's talk about two options for the small business iPhone users who are eager to get full smart phone and mobile computing advantages from their new shiny faced toy, er, iPhone.

Neither option includes Microsoft Exchange, saving money and time while supporting the miracle of communication (at least according to Apple).
