I hope we don't have anything too funky when it comes to splitting up the apps.
Categories? Stacks? Folders will do just fine. Click a Games folder, see the games slide into view. Want to go back up, slide your finger or press the Home button. Can't be any simpler.
Call me a PITA dad, but I really want more parental control - maybe even remote administration from the master account on MobileMe. Disable games or certain apps/features if it's past curfew or if they're grounded. Call screening, whitelists, blacklists, for incoming and outgoing calls and SMS. Ability to get location, either 24-hour history, last polled or current, and show in Google Maps. Remotely snap a picture, answer a call (monitoring), or send a siren sound.
How about instant media messaging right from the in-call screen? Say you're on the phone with your wife, girlfriend, or friend. You're at the store and don't remember which brand or style of shirt to get. An additional icon will join Mute, Keypad, Speaker/Source, Add Call, Hold, and Contacts and be labeled "Send Photo." Instantly pulls up the camera and sends to the person (or persons if it's a conference) on the other end of the call, either via MMS (preferred) or email. Sure beats having to press Home, then Camera, take a picture, then click the Action icon, Send Email, look up or type the email address, click Send, then click Return to Call (whew!).
How about selective deletion of call history?
Or what about reverse phone lookup when someone calls? For 3G users, it's a no-brainer, since it can do voice and data simultaneously (take that, Verizon/Sprint!). It may take a few seconds before it can find it, but it'll be worth it. Even if it's just location and carrier, but would be nice if it would try to pull it from Google and give its best guess. Sure helps when you're looking at the call history and for those random-looking numbers you didn't add to your Contacts and name them, this would be a great help.
By the way, I sent these to the Apple iPhone Feedback page. Let's see if they'll respond or even read it.
