Dear Auntie TUAW,

I was driving home from an appointment today with my brother, and at a stop light, I noticed that instead of the Edge "E", I had this little blue dot. I just assumed that it was where i had connected to WiFi and had no bars, but it was much too big and centered.

My brother, who also has an iPhone, pulled his out to find that we both had the little dot. They are both first Gen iPhones, his 4GB, mine 8GB. I did not know what this meant, but being the Apple nerd I am, I figure I would have heard something of this dot before now.

Do you know what it is? Could it have something to do with 3.0 coming out soon as expected? Thanks, And I look forward to hearing what you think.

With love from your nephew,

Andrew Dixon

Andrew, sweetheart,

Speaking of the iPhone, are you including enough roughage in your diet? Now that I'm entering onto what we oldsters can only term our "tender years," I've grown to realize that bulk, bulk, bulk is the key to world happiness. Fiber is health; health, fiber. That is what we know at TUAW, and all ye need to know for better digestive function.

As for your question, that little blue circle means you youngsters were connected to a GPRS network, aka General Packet Radio Service. When the iPhone first debuted, it displayed the EDGE "E" when connected to GPRS. This made pedants cry. Newer firmware versions show this blue circle instead. As noted below, GPRS is quite a bit slower than either EDGE or 3G.

To check this icon out for yourself, you can browse through your iPhone files using sftp (on a jailbroken iPhone) or iBrowser (for iPhones with the developer deployment). The EDGE and GPRS icons live in /System/Library/CoreServices/SpringBoard.app and are named FSO_EDGE_ON.png and FSO_GPRS_ON.png. You'll need to convert the compressed iPhone-style png images to Mac compatible ones using a utility like fixpng.

Send my love to your brother and don't forget to wear a scarf to keep your neck warm!

Love and hugs,

Auntie T.

In a shot across the iPhone's bow, Palm is launching its new Palm Pre smartphone the weekend before Apple's Worldwide Developer Conference. This means any iPhone announcements at WWDC will be undoubtedly compared to Palm's new platform.

The Pre handset will cost $200 after a $100 mail-in rebate, and if you sign up for a two-year contract with Sprint. The monthly service costs roughly the same as AT&T's iPhone plan but offers unlimited text messaging -- a $20 option with Ma Bell.

Electronista points out that the Pre has some small technical advantages over the iPhone as well: a three megapixel camera, an optional inductive charger, and EVDO networking. Depending on the area, EVDO can be faster than both EDGE and GPRS, but not faster than HSDPA (the latter of which AT&T is rolling out across the U.S.). In any case, AT&T is already preparing its sales staff for the looming battle.

Also, Sprint claims that having a Pre will cost $1,430 less over the two-year contract period compared to owning an iPhone for the same period.

Meanwhile, for those of us on Verizon, we'll just have to make do with calculators connected by string. Which reminds me -- you all got the notice Verizon was upgrading us to nylon cord this week, right?

Fortunately, AT&T Wireless has a list of the major markets that have HSDPA service. Unfortunately, you have to go through the list by state and city name before you can actually click on a map and see if your house or office is in a zone of 3G love. My house, which has sucky AT&T service at this time, is allegedly in a 3G-happy area (blue on the screenshot). That's the good news. The bad news is that I'm right near the border of one of those orange zones, which indicate no 3G service.

My sister currently enjoys EDGE service in her home town of Richland, WA, but is anxious to get her iPhone connected with 3G service. I hate to tell her that she's not on the list.
