Anandtech compared the differences in signal mapping between iOS 4 and iOS 4.0.1 (and iOS 4.1) and concluded that Apple has indeed produced a much more reliable system (meaning the old system was less than honestly reporting strength):
As you can see the old way (top) put far too much weight into the 5th bar of signal. Apple's new approach not only splits it up more reasonably between the 4th and 5th bar (still non-linearly keeping you in the 5th bar if possible) but also extends the range of the lower bars.
Calcbot is a universal calculator application for iPad and iPhone. It is a basic scientific calculator but is designed well with big buttons and tape. For this review, we will be focusing on the iPad version.
In landscape, you will find the calculator on the left and tape on the right. The calculator has two pages of buttons which keeps them nice and big. Just swipe the calculator to the left to bring the next page of functions. The first page is primarily numbers and basic operators as well as power and root functions. The second page contains a more functions such at the specific powers of 2 and 3, square root, factorial, log, natural logarithm, exponential, and trigonometric functions. Tapping the shift key (up arrow) will change the trigonometric functions to their inverses. Calcbot lets you chose between radians and degrees as well. The second page does not include an equal sign. This is annoying because a calculation does not appear on the tape until the equal sign is tapped.
If you want to re-enter a calculation from the tape, just tap the desired calculation and a menu pops up to use result, use expression, copy, send in email, or delete. You can also swipe to delete any expression. To email or clear the entire tape, tap the wheel in the upper right hand corner. If you're not interested in seeing the tape, rotate to portrait mode to view only the calculator.
Calcbot is an excellent little calculator app that looks and works great. There is nothing fancy about it, but that's part of it's appeal. Calcbot is strait-forward and to the point which makes it easy and intuitive to use. Simply put, Calcbot is another visually appealing and terrifically designed app by Tapbots.
The bad press continues to mount for Apple but this time it was not from David Letterman or Top Gear rather the TV show The View. Whoopi Goldberg described how she took out her frustration of the constant poor performance she has had with her iPhone 4. Exactly how did she destroy you ask - opened her car door and smashed the phone onto the ground.
Luckily my iPhone 4 works pretty well, though I'm sure I would be rational enough not to smash my device on the ground.
Bloomberg is reporting that "someone familiar with the matter" is claiming Apple's very own antenna expert, Ruben Caballero, warned the company of possible flaws that could have created the issues so many of you are currently experiencing - dropped calls and reception problems.
iPhoneHellas.gr is claiming they've heard Apple will release iOS 4 later today. They've gotten that kind of stuff right before, and Apple does have an iPhone 4 press conference scheduled for tomorrow, so the timing would make some sense. iOS 4.0.1 being released would mean the changes to the way bars are shown and reported in the developer beta for iOS 4.1 would be public and could be stated as such by Apple.
It would be a couple weeks earlier than Apple's usual end of July/beginning of August iOS x.0.1 update cycle, but likely welcome by those suffering proximity sensor issues and other iOS 4 bugs.
iOS 3.0 introduced A2DP (advanced audio distribution profile) stereo bluetooth playback to iPhone but for some reason Apple never added the accompanying AVRCP (audio/video remote control profile) to go with it... until the new iOS 4.1 beta.
Basically, in iOS 3 and iOS 4, you could play and pause music and other audio but you couldn't control things like volume. The buttons on the Bluetooth device simply didn't work. This was a show-stopper for many users who wanted and needed that kind of control -- for example, to use while driving.
New York City Mayor Michael Bloomberg is using his iPad "night and day" for both work and pleasure. According to Deputy Mayor Howard Wolfson, "he takes the iPad with him everywhere. He uses it all the time." He even had it accompany him during his visit with Queen Elizabeth last week.
The mayer uses his iPad to read speeches, keep notes, obtain briefing materials, check the weather, get directions with Google maps, and read books and magazines. Bloomberg has a goal to go paperless and the iPad his helping him do just that. However, his staff does keep a briefing book for him as a backup.
