Over at Mac Rumors they've unearthed a recent patent that shows Apple is researching cleverer use of the iPhone's many sensors. More nifty than turning the screen off when you put it to your ear, the new uses may include things like working out it's in your pocket (by temperature, proximity and ambient light) and then auto-switching to vibrate mode. Intriguingly, there's a hint that by detecting you've docked the phone, it may pass an ongoing phone call to a VoIP call over iChat. This all makes sense: making best use of those sensors and the iPhone's power... but like all Apple patents, we may never see these ideas in a real-life software update. [MacRumors]
You CAN send and receive MMS messages on an iPhone. Just send it to the phone's email address (firstname.lastname@example.org). It is free (for you) and easier to do than sending an MMS on most regular phones. Also, if you want to receive an MMS message, have them send it to your email address instead of your phone number. Here is a list of the different email extensions for various wireless carriers.
Also, if you want to get out of your Verizon contract, simply take a look at Verizon's coverage map on their web site, find a town where they don't get coverage, and then tell them you will be moving there next week. Sometimes they will ask for proof of your new address, but it worked fine for my friend last year. Other ways to get out of your contract include killing yourself, joining the military, or using your cell phone outside of Verizon's network on a regular basis. Cell phone companies put clauses in their contracts that allow them to opt out if you are constantly roaming because it costs them a lot of money.
