I'm not going to trawl back and try and find the articles, unless I have to, so I'll assume most of you here understand this already 
The iPad1 has slow WiFi speeds, due to Apple, Something to do with channels and number of antenna's, making the iPad's WiFi, one could say, a bit on the cheap.
It was boasted as a N class device, but it was kind of fudging the truth a little as due to the physical design it could not run at full N speeds one would get with a Mac or Windows laptop or a desktop on wireless.
This was known about and well documented, if I REALLY have to find the articles again that explain it all.
So, knowing this, my question:
As we are now on iPad3 have Apple actually sorted this out now and has the latest iPad now been build/improved/fixed? to run at what we would consider full Wireless N speeds that other devices run at.
Or are Apple still, crippling it's WiFi speed due to their design?
Here is a little bit of the text relation to Apple's, ahem, playing with what standards mean from the iPad1 model:
Apple's technical specifications for the iPad say that dual-band (2.4 GHz and 5 GHz) 802.11n is supported. And it is. But what Apple doesn't tell you is that the version of 802.11n built in to the iPad is such that you get almost no speed improvement over 802.11g or 802.11a.
To understand what's going on with the iPad's mediocre 802.11n design, you have to understand a little bit about what goes in to 802.11n. There are three 802.11n improvements that bump up the maximum data rate from the 54 Mbps we had with 802.11a/g: more efficient (5/6 instead of 3/4) OFDM coding, double-wide (40 MHz instead of 20 MHz) channels and MIMO antenna systems (for spatial multiplexing). (And yes, I realize that the short guard interval can also improve data rates, but let's pretend we live in a world where there is always a legacy a/b/g device sharing our BSS.) Let's talk about each of these things individually and whether the iPad supports them.
