[Note: If you want to receive e-mail or SMS, skip the "Prowl" part. Growl has the ability to send e-mail without using Prowl. Note that Prowl is a paid app for iPhone (Howl is another good one).] Okay, someone mentioned in one of the White iPhone 4 threads that they had written a script to check the Apple website for changes and send them a text message. I'm not knowledgable enough to write a script like that, but I have found an awesome solution for Mac users who want to receive a push notification (or e-mail, or SMS) on their current iPhone when the Apple site changes. Basically, this involves using a combination of the programs "Changes Meter," "Growl," and (optionally) "Prowl (or Howl)." Changes Meter monitors websites (any website) for changes at any interval you specify. Growl is a notification manager for Mac OS X, and Prowl (and Howl) are iPhone apps that will send you a push notification anytime your desktop receives a Growl notification. First, download Changes Meter from here: http://intuiware.com/products/changes-meter Next, download Growl from here: http://growl.info/ Finally, (if you want push notifications) create a Prowl account and install the Prowl plug-in (or check out Howl instead): http://prowl.weks.net/installation.php It's all fairly self-explanatory, but you'll need to add the website you want to monitor into Changes Meter. I used the URL that comes up when you click "Buy" on the iPhone 4 page on apple.com, as well as the search results page from searching the string "white iphone 4" on the Apple store site. You'll need to go into Preferences in Changes Meter and make sure Growl notifications are enabled. You'll also need to go into Growl and make sure you've selected Prowl (and entered your Prowl username/pass) as the notification style for Changes Meter (or MailMe if you want e-mail). If you want to receive SMS, I recommend using MailMe and send the SMS as an e-mail. For example, for AT&T phone numbers your address is your 10-digit phone number @txt.att.net (similar addresses exist for other carriers). Finally, set up the Prowl (or Howl) app on your iPhone and test the setup by monitoring a twitter feed or something that changes frequently. It works great!
