AT&T is giving some concession to keep the old unlimited iPad data plan — but the offered reason that very few people are using the full 5GB/month data cap doesn’t seem to hold water, especially with video calling coming. On the other hand, the claim that the new pricing will be more affordable for more people sounds like a spin on “we’re losing exclusivity soon, so we want to prevent financial bleeding before the fact by offering the lowest-priced data plans now.” Will Apple slap AT&T’s wrists over this ? Not sure, but by Monday, we should at least know what consumer electronics wonders Steve Jobs has in store for the rest of 2010, after Jobs’ keynote kicks off in the morning at WWDC.

Of course, it’s still fun to speculate until then, and now speculation is running towards multiple iPhone carriers in the USA, though not immediately. This is based on speculation about what Jobs meant at D8 this week when he said there might be an advantage to this, as well as other rumors that suggest AT&T’s exclusivity contract is coming to an end in Nov or thereabouts. This might be why AT&T has suddenly created several revenue stream opportunities for themselves around the iPhone and iPad, including specialized iPhone insurance, increased ETF (Early Termination Fee) rates, revised data plans that do not favor power users (i.e., probably most early adopters of the iPad), etc.

Other interesting tidbits out of D8: that the iPad concept predated the iPhone, and that the original project was called the Safari Pad. I guess the Newton was missed.

There’s been yet another “leak” of a possible prototype of the 4th-gen Apple iPhone. A photo (above) shows both a black and a white phone with larger screens. Given all the rumors and SDK evidence, it seems obvious that the OS 4 iPhone will have video calling and the larger screen resolution necessary to pull that off.

Fortunately, in just 2 weeks, all the speculation will be put to rest when Apple’s 5-day WWDC (Worldwide Developers Conference) kicks off on Jun 7th. Steve Jobs will start the event off with a keynote address to over 5,000 developers at the sold-out event. There’s an email circulating around the Web that’s supposedly from Jobs telling someone that “you won’t be disappointed,” in reference to what he’s probably planning to announce at the conference. I.e., probably the new iPhone, other features of the new SDK, and a mention of the countries where the iPad will by then be available.

What Jobs might not know is the new but celebrated iPad hasn’t only been banned in some countries but also in New York’s Yankee Stadium of all places. Apparently the stadium’s security policy considers the iPad to be in the laptop category, and laptops are not allowed in the stadium.

Has anyone told Yankee Stadium security that even the TSA (Transportation Safety Authority) differentiates between iPads and laptops? That’s actually a very disappointing fact. If more venues ban iPads, then carrying a tablet computer around might not become a common practice. I carry my iPad with me wherever I go, almost without fail. Now if I’m driving, I could always leave my iPad hidden somewhere, but if I’m walking or taking public transit — which is very likely in New York — then what am I supposed to do with it? Considering London will have full Wi-Fi access for the 20102 Olympics, I’m guessing they won’t be banning the iPad at venues there. Well, given that many Apple stores are sold out of the iPad, especially the 3G model, I’m guessing not a lot of people are going to be worried about this sort of ban, at least for now.

Is Apple stealing the market? Google announced last week that they were shutting down their online store and now Nokia is closing their flagship New York store. The Chicago store, on the other hand, is not closing. Wait a minute; doesn’t New York have a larger population than Chicago? Wouldn’t it make more sense to do the closing the other way around?

AT&T just got the Palm Pre Plus, but they’re charging $150 for it despite Verizon’s lower price. However, if you’re a new AT&T customer, you can get the phone for $50, but without the free Palm Touchstone charging dock. AT&T’s Pixi Plus will be available Jun 6th, to join the new AT&T Palm Pre Plus. The free Touchstone charge deal doesn’t apply to the Pixi Plus [Engadget]. If you get any smartphone from AT&T, be forewarned that they’ve increased the early termination fee from $175 to $325, effective Jun 1st — whether you’re a new subscriber or renewing your service.

The U.S. FTC finally approved Google’s purchase of mobile ad network AdMob Inc. While it took them six months to approve, the decision was partly to do with Apple’s own purchase of ad network Quattro Wireless. If I’m not mistaken, Apple’s purchase will result in their iAd network, announced at the same event earlier this year where Steve Jobs revealed some of the features that iPhone OS 4 would have.

The iPad might have a very long lasting battery but most smartphones seem to fizzle out in just a couple of hours of use. For example, the Palm Pre Plus I bought for it’s Mobile Hotspot feature (to power my WiFi-only iPad), has a battery that dies long, long before the iPad. But Google’s Larry Page recently said that if your Android-powered device isn’t lasting a day, there’s something wrong with your apps.
