Enterprise users have long been begging for an iPhone of their own - meanwhile, their IT departments have been flatly refusing, quoting not only the difficulties in securely hooking up a consumer handset to a business network, but also AT&T's general reluctance to offer non-consumer tariffs.  Well, according to a tip-off to The Boy Genius Report, AT&T are planning to announce business and corporate accounts for the iPhone on January 21st, requiring special data plans starting from $25.

While the iPhones themselves won't be subsidised, any corporate discount your employer might have negotiated with AT&T will still apply.  There's also talk of a pre-activation procedure that must be followed before hooking the handset up to iTunes in the usual fashion.

Available to both current and new account holders, you'll of course need to be a business or corporation to apply.
