FreePress Still Wants It Both Ways

Josh Levy over at FreePress is very, very excited today because it has been determined that jailbreaking your iPhone is not a violation of the Digital Millennium Copyright Act. This of course in his opinion is a huge win for openness and will of course (I wish he would explain how.) lead to open wireless networks.

Pundits not among 73% of iPhone users who love AT&T

If all we went by was the media (including TV, blogosphere and tech sites), we would likely believe that AT&T is the worse wireless network operator in the world.  The Yankee group decided to test this theory but they seemed to have found the opposite where 73% of iPhone users loved their AT&T wireless service which is [...]

Apple gets the profit, AT&T gets the blame

Fred Vogelstein at Wired has written a very interesting piece on the iPhone partnership between Apple and AT&T. Apple (and Google) are producing devices that are exploding in popularity and bandwidth consumption while the network operators have to invest boatloads of money just to keep their noses above water all the while taking a brutal public relations bashing.

Wireless mesh networks have never been practical for commercial deployment and they never will be. This article explains why mesh networks have such poor coverage and poor throughput performance.

Software fix seems inadequate for iPhone 4

Not surprisingly, it would seem that the software update isn’t going to fix the antenna issues on the iPhone 4 and the bad P.R. keeps piling on.  The pressures are mounting as Consumer Reports issues a warning against buying the iPhone 4 and even the late night TV hosts are getting a few laughs at the [...]

The Graph That Explains The End Of All-You-Can-Eat Data Plans

I was taking another look through Morgan Stanley’s Mobile Internet Report from December and a graph caught my eye that pretty much sums up the reason mobile carriers are doing away with the all-you-can-eat pricing model. It’s somewhat hard to see in the image above, but if you’re interested, click through to the report and [...]

Tiered mobile services could mean half price for most users

There are many people in the blogosphere and policy space that oppose mobile data usage caps like the one that AT&T recently implemented, but they don’t seem to understand the reasoning. AT&T stopped offering their $30 unlimited iPad and iPhone data plan and changing to a $25 2-GB plan and a $15 200-MB plan, and some believe that this is merely a shameless profit grab that overcharges customers for overages. But when we look at the actual data, it would seem that these conspiracy theories are unfounded.

Apple blames signal display software

Apple has released an official letter saying that the signal problems are due to faulty software showing 2 bars as 4 bars. The problem is that this won’t solve the real problem of bare hands touching the lower left corner of the phone.

iPhone 4 Wi-Fi performance benchmarks

We were surprised to see that Anandtech only managed to get Wi-Fi performance of 7.2 Mbps downstream and 7.96 Mbps upstream using the SpeedTest.net app for iPhone OS. We ran our own tests and found that the iPhone 4 can sustain 20 Mbps over Wi-Fi. These are much better results, but they fall short of optimum 802.11g much less 802.11n.
