Paying for your morning latte just got easier with the new Pay with Square app, which allows users to pay for purchases without swiping their credit card. Instead, users can pay for their purchases directly with their Android or iPhone. The app can be downloaded directly from the Apple App Store or Google Play. Users must be running at least iOS 4.1 or Android 2.2 in order to use the app.

It’s no secret that I love my T-Mobile Sidekick (while the hardware manufacturer, Danger, calls it the “HipTop”, the only place to get it, T-Mobile, calls it the “Sidekick”). While legions are wondering whether their Blackberry service will go the way of the wind, or are dealing with getting their email to POP or iMap to their Treos, my Sidekick does everything I want it to do, and more.

If your Blackberry isn’t working, you’re not alone. Neither is anybody else’s. In fact, Research in Motion (RIM) is experiencing what may be their largest network outage ever, affecting users of their (overly)popular Blackberry device around the world. Reports from the U.S., Canada, and the UK abound.

Wow, that was fast! It was barely a week ago that we predicted the convergence of GPS and Internet on cell phones and it leading to location-based push advertising to your cell phone, and now Nokia has announced (well, leaked, really) that they plan to have full navigation GPS on all Nokia cell phones.

Here is my prediction: the next big thing from the Internet advertising point of view is going to be this: the convergence of always-on Internet and GPS in one device. Internet and GPS convergence.

Blackberry thumb is the name for a new malady afflicting thousands of Americans, and probably millions around the world, each day. Blackberry thumb is a repetitive stress injury to the thumb brought on by too much texting – typing on tiny keyboards on PDAs or cell phones. If you must do a lot of text entry on your handheld or cell phone, consider getting a folding bluetooth keyboard

This is a side-by-side review and comparison of the Sidekick 3, the Treo, and the Cingular 8125. I just came off strenuously testing a Treo 650 and a Cingular 8125. Why? Because I was so discouraged when they finally added Bluetooth to the new Sidekick 3 but crippled it so that all you could use it for was headsets and xfering a vcard. Here are the results.

The new Tmobile Dash phone is the newest device in the combined cellphone and PDA market. With built -in wifi and bluetooth as well as being a GSM phone, the T-mobile Dash allows you maximum connectivity in a mimimum-sized package.

The new Sony Reader is an eBook reader introduced by Sony that is about the size of a paperback, but weighing just 9 ounces. The Sony Reader works with the Connect service, which is like iTunes for books. With 64mb of memory on board, and an expandable memory card slot, the Sony Reader is capable of carrying dozens of ebooks at once.

We think that you can’t go wrong with the Sidekick hand held Internet email device. For our money, it’s the best handheld Internet email device on the market today.

The new T-Mobile Sidekick 3 (not Sidekick III, no Roman numerals here!) came out this week, and our ongoing testing has revealed that the Sidekick 3, despite being Edge capable, is not actually yet on an Edge network. And if you want it, it will cost you.

For what bluetooth services the T Mobile Sidekick 3 offers, it’s quite decent. Of course, it doesn’t have voice dialing. And it doesn’t stop there. Because it also doesn’t have any of the standard bluetooth services which you can get on pretty much any bluetooth-enabled phone now. Such as, you know, file transfer!

You can find an online users manual for the T Mobile Sidekick 3 at the Danger site (it is, after all, really the Danger Sidekick). To get online help for the Sidekick 3 (not the Sidekick III, as they did away with the Roman numerals with the Sidekick II), go here.

A Sidekick 3 by any other name (Danger Sidekick, Sidekick Phone, T-Mobile Sidekick – just not Sidekick III, please!) is the hottest new device to hit the streets. Complete with its own Sidekick 3 backgrounds (wallpaper) and its own Sidekick 3 bluetooth, here is a side by side comparison and review of the T Mobile Sidekick 3 (not the “T-Mobile Sidekick III” because they did away with the Roman numerals).

After “buying” a stolen Sidekick, Sashacristal8905 at AOL used the stolen Sidekick to log into her AIM account, and take pictures of herself. And then was surprised when she was tracked down, and threatens the rightful owner! So does her brother, WarriorPena84, who is an MP in the Army.
