it doesn't seem to matter how good Windows Phone 7 is. Microsoft's smartphone market share continues to plummet.

Four decades ago, Intel created the first true microprocessor. We're all still trying to catch up.

Apple has shrewdly avoided the boneheaded arrogance it displayed during the iPhone 4 antenna fiasco, and admitted forthrightly that the new iPhone 4S has distressingly brief battery life. The company says it's a software issue that it will soon repair.

A new study finds that cell phones don't cause brain tumors. Well, all right then.

Fragile or not, the iPhone 4S is selling like wildfire. Wasn't this phone supposed to be a major letdown? Seems only the "experts" felt that way. Other people were too busy getting in line to buy one...

A gadget insurance company stress=tested the new iPhone 4S, with tragic results.

...if you're in California. The governor there just vetoed a bill that would have required cops to get a warrant before viewing the data stored in a suspect's phone. So now, a cop can just take your phone and start skimming through whatever he finds there.

The Wall Street Journal reports that Sprint will buy $20 billion worth of iPhones over the next four years, in a "bet the company" bid to stay competitive with AT&T and Verizon Wireless.

The company's WiMAX-based 4G service can't hold a candle to Verizon's LTE technology, and so Sprint is racing to deploy an LTE network of its own.

At last Google Wallet is here--the company's long-awaited technology that lets users make purchases using a smartphone as if it were a credit or debit card.

For now, the service is available only for Sprint cellphone customers who happen to own the Samsung/Google Nexus S phone. I actually own the right phone but I subscribe to the wrong carrier--AT&T.

Do I really want to pay for groceries this way? Let me think about it...

A new Android app from Sprint prevents phoning while driving, by locking the phone when it detects that the user is in a moving car. The service costs $2 a month, and a BlackBerry version is pending

Well, duh. The company refuses to test Android apps for viruses and other nasties, with the result that the bad guys are racing to write attack programs targeting Android phones and tablets. I got my Android phone for free, but unless Google gets a handle on this, I may regret it.

Looks like Sprint won't be offering cellphones that run Hewlett-Packard's WebOS operating system, the same software that runs on the Palm Pre phone and the HP TouchPad tablet.

So Samsung's Galaxy Tab tablets aren't selling very well after all? Well, considering they're about as expensive as the superior iPad, why the heck should they?

A million sold, so far. I guess many consumers don't share my reservations about the Galaxy Tab--mainly that it's too expensive. Still, it is a nice device despite the price and other limitations.

One analyst says that sales of the Galaxy Tab are falling short of expectations, but so are those of Apple's iPad. Hmmm...

Samsung's Galaxy Tab is a capable rival to Apple's iPad. But its high price and lack of good apps ensure that it won't cost Steve Jobs any lost sleep.

Location-based services like Foursquare really aren't too popular, according to this report. Sure, all the cool kids like to talk about "checking in" and becoming the "mayor" of this nightclub or that coffee shop. But most folks don't see the point. I used Foursquare myself for several months but have lately wiped it from my BlackBerry without regret. Does me no good that I can see, so why bother? Besides, why should I report my movements to Foursquare? Go hire a private eye if you're that interested, but you'll get no help from me.

The new high-speed wireless data services from cellular carriers Sprint and T-Mobile don't fully deliver on the promise of superfast 4G technology. But they're still worthy improvements over what we've got. Here's my take on the new services, which have just launched in Boston.

Sprint unleashes its 4G cellular data service in Boston, but rival T-Mobile says its improved 3G service, also just launched, is equally fast. Let the high-speed data flow like wine!

Speaking of Sprint's 4G service, I never got above 3.5 megabits per second when I tested it in Baltimore. But it seems that Sprint's newest 4G phone, the Epic, pumps the data a whole lot faster...

At long last, Boston's about to get 4G wireless service, thanks to cell carrier Sprint and its partner Clearwire. At last, those EVO 4G phones will get a chance to strut their stuff...

The embattled cellphone company actually gained customers last quarter, partly due to the popularity of the EVO 4G Android phone.

Only...not in Boston. Faster, please.

Carry a spare, says Sprint CEO Dan Hesse. Seems a bit onerous, but there's no denying that short battery life is the EVO's biggest flaw.

Sprint is selling its EVO 4G phone faster than its supplier HTC can make them. That could be bad news as Sprint rushes to launch 4G in lots more cities, including Boston. Sprint's for real about this--the roof of my own condo has just been rented out to Clearwire, the Sprint subsidiary that delivers 4G service. Guess my reception ought to be extra good...

Sprint's 4G data service keeps popping up in more and more US cities. Just not the city that really matters. Get a move on, guys.

Remember how Sprint said that first-day sales of the EVO 4G phone set some kinda record? Well, maybe not.

I fly to Baltimore to check out America's first 4G phone, and I (mostly) like what I see.

Blogging has been a bit light. I'm on the road testing the new Evo 4G phone from Sprint. Dearie me, this is nice. Details to follow...

According to this Reuters story, next generation cellphones and 4G Internet service may become widely available faster than you might have expected. Consumers have fallen in love with high-speed wireless, and carriers are eager to cash in.

Sprint's new Evo 4G is the first 4G phone to hit the US market.  And it's landing very soon indeed--Friday, June 4. 

This Android phone will let users connect to the Internet at speeds approaching those of home cable modem service--5- to 12 megabits.  And it works as a WiFi hotspot, so you can share your bandwidth with up to eight nearby users.  But this extra speed will come at a price.  Sprint will charge its 4G users an extra $10 a month.

If the Evo 4G lives up to the hype, it'll be worth it.

I want me one of these.  Unfortunately, Sprint 4G service isn't available in Boston yet.  But imagine an Android smartphone with cable-modem type speeds, capable of downloading data at up to 10 megabits, and also capable of serving as a wireless hotspot for other phones or laptops in the same room.  Exceedingly cool...

Now RadioShack has decided to stop selling Palm's beleaguered Pre and Pixi phones.  These guys just can't catch a break.
