Recently I attended a blogging convention and learned all sorts of cool information on what you can do to make life easier with Twitter and your mobile phone.

First you sign up for a free Twitter account. Then go to settings->devices and follow the directions to add your cell phone.

Then you can:
1 ) Send appointments to your Google calendar. Add GCal as a friend (follow ) in your Twitter account and grant access to your Google calendar here. Then you can text from your phone to 40404 d gcal meeting Tom 7am tomorrow and your appointment will be added to your Google Calendar.

2 ) Write reminders for yourself, text ‘pick up milk’, ‘don’t forget to pick up children’, etc. You can look at your Twitter account anytime from your cell phone and see your list of things to do.

3 ) Leave notes for your family and friends. Text a twitter ‘running late’, ‘kidnapped by aliens’ etc to let everyone know what’s happening with you. It’s easier than texting everyone.

I’m still getting the hang of Twitter and finding uses for it. It’s far more useful than I thought it would be. Don’t be the last on your block to get a Twitter account because all the good user names will be gone soon.

You can also use Twitterfone to do all this by voice from your phone.

Now you can be shopping at a big box store, especially those known to have several prices on things, text a product name, bar code or upc number to Amazon and receive back their product listing and price. From there you can purchase it from Amazon or continue your purchase at the local store.

“With today’s launch of TextBuyIt, any Amazon.com customer can now use any mobile device to shop and buy from Amazon.com, at anytime, anywhere they are,” said Howard Gefen, Director of Amazon Mobile Payments. “With TextBuyIt, if you’re walking out of a concert and want to buy a CD from the artist you just saw, or if you’re at dinner and a friend tells you about a great book you should read, all you have to do is get out your mobile device, send a text message to Amazon, reply to the response, confirm your order, and your item will be on its way. It’s incredibly simple and convenient.”

In less than a minute and using only text messages, Amazon.com customers can find the product they are looking for and complete a purchase using TextBuyIt. Simply send a text message to “AMAZON” (262966) with the name of the product, search term or a UPC or ISBN code, and, within seconds, Amazon replies with the product or products that match the search, along with prices. To buy an item, customers simply reply to the text message by entering the unique single digit number next to the item they want. Customers will then receive a short phone call from Amazon with the final details of their order and asking them to confirm or cancel the purchase.

When customers choose to purchase something for the first time using TextBuyIt, they will be asked for their e-mail address and shipping ZIP code they use for their Amazon.com account. With this information, Amazon uses customers’ default settings for payment method, shipping address and shipping speed, including 2-Day shipping for Amazon Prime members.

Just be careful not to announce such bargains to fellow shoppers or Best Buy might have you arrested.

Best Buy called the cops on Alex because he told another shopper that the Jawbone headset he was considering was poor quality and marked up $30 from the manufacturer’s price. [ read more Best Buy calls cops on your for telling fellow customer jawbone headset is overpriced ]

First you must register your phone number with the pizza restaurant. When you register you can set up your favorite orders on the website. After that just text the restaurant ( 749hut for Pizza Hut ) and tell it you want to order your favorite pizza ( O FAV )

It doesn’t get any easier than that.

You can also go to Mobile Dominos Website and order or order from the regular websites for Papa John’s and Pizza Hut.

You can also set up your Google Calendar to send you text reminders of appointments
