I love my iPhone, can pretty much login to any interface to perform quick stats updates or action any campaign that's gone sideways.
The rumored updates for this summer's release supposedly add:
Video Recording
Copy/Paste
Faster Cellular Network access (rumors are like double, but obviously not 4G since AT&T hasn't completed their upgrade yet) from 3.6 to 7.2Mbps
The first two updates are available if you jailbreak your phone but the speedbump would be pretty awesome.
iPhone has video recording as long as you're willing to jailbreak it, which is no big deal with quickpwn.
iPhone Video Recorder - DreamCatcher Official Site is the site. Download the trial, and then if you search enough like I did, you can find a crack to make it full version so you don't have to pay the $20.
The video it records is great. ...though yeah, it'd be a lot better if it were included officially in an update of course.
