For iPhone users who are jealous of the webOS Palm Pre users who get multiple Exchange account support, there’s good news as there’s a jailbreak app for multi-Exchange account support for iPhone users. The caveat here is that your iPhone needs to be jailbroken, and if it is, you can navigate to the jailbroken app store–Cydia–to get “AddExchange” installed onto your device. Each Exchange account will have its own calendars, contacts, and mail settings to keep things separate. If you’re already an Exchange user on Apple’s iPhone, you can use AddExchange to add Gmail Push using Google’s mobile sync protocol to have push for work and pleasure as well.
