35 Percent of Fortune 500 Companies have signed up and participated in Apple's iPhone enterprise beta programme and Steve Jobs is betting on the diminutive device to spearhead Apple's success in the corporate market where the Fruity brand has not enjoyed as much success as in the consumer market.
And O2's newly published Business Tariffs for the iPhone means that things are getting serious and RIM's Blackberry could soon feel the heat from Apple; the UK telco partner for Apple has lined up a whopping nine separate tariffs to cater for all business needs.
The Best for Business PAYU offers a 8GB iPhone for £84.26 but charges you a whopping 30p per minutes for calls to other mobiles and you would still need to fork out £26.91 per month over two years - definitely not the best deal.
For £4 more per month, the Small Business Regular user is a much better offer with 300 minutes and 50 inclusive texts as well as unlimited O2 calls and unlimited calls to 10 standard landlines.
Moving up to Small Business Frequent User, which costs £34.76 on a 3-year contract, gives you 450 text messages and 700 minutes and a free 8GB iPhone to boot from.
Another intriguing addition to the tariff grid is the iPhone Sharer which allows secondary users to join in a primary user and, as the name implies, share minutes and texts.
At the other end of the spectrum, the Super User package appears to be by far the best package ever to have - £90 per month (with a three year contract) gives you ultimate everything with 1000 minutes of calls to Europe.
Note that you won't be able to combine iPhone sharer and Super User accounts.
