★★★★★ “I am thrilled to have this tool. Thank you to the developers of Big Photo.” – HallYoung@Art, USA

“An undiscovered gem of utility” –

★★★★★ “Great app that resizes photos to 200%+ their original size without ruining their quality. Resulting output is similar to that of resizing algorithms in Photoshop. I use this app daily and it always gives me what I want in a timely, stable manner. This app is truly a useful and prized tool in my arsenal of photo apps.” – M., U.S.A

★★★★★ “5 stars for ability to zoom in really close and crop a small portion of a photo in high quality and custom dimensions. The slow and clunky user interface has been fixed in the recent version. It is now a joy to use, and tremendously useful.” – Maria, Greece

★★★★★ “There are a number of creative apps that are really useful but lack decent resolution output. Big Photo does an excellent job or sampling up and making those other apps more creatively useful… For the iPhone camera output and other ordinary camera apps shooting at the standard 8 million pixels the software easily deals with scaling up with great results. A much needed tool for mobile art and photography. Highly recommend.” – Poetry, UK


In addition to access your Camera and existing Photo Library, Big Photo also provides document interaction support so you can launch Big Photo to handle pictures or images from within your other apps that support document interaction.

Better yet, for advanced users, you can transfer your pictures between your PC/Mac and Big Photo’s iTunes File Sharing folder. For instructions how to use iTunes File Sharing, see

Support file formats:png, jpg (jpeg), gif, tif (tiff), bmp, ico, cur, xbm.

Answer: In Resize menu, you do not change any size or scale, just change to DPI to your desired number, then click “Resize” to generate a new picture which has different DPI & the rest is the same.

User Agent for Web Explorer

In the world of web browsers, “User Agent” is used to identify the web browser, i.e. browser engine, version, running OS, device types etc.

When a website receives web page request from a web browser, it may send back different content for different web browsers. For example, will return at least three different home web pages for mobile Safari running on iPhone, mobile Safari running on iPad, and desktop Safari running Mac. The reason, it will be presented on different devices for best layout and viewing experiences. Another reason, mobile Safari does not support Adobe Flash, but desktop Safari does. But mobile Safari can play HTML 5 videos, so the web site will send a customized content to mobile Safari. Because the screen sizes of iPhone and iPad are different, Yahoo will send different versions of its home page to iPhone users and iPad users. When your browser requests a web page, it will send a “User Agent” string to the web sites to give the browser information. Based on your browser’s User Agent string, web sites will know what kind of browser you are using, then best version of the requested web page will be sent back to your browser.

How about if you want to view desktop version of Yahoo home page on your iPhone?

“Web Explorer” supports “User Agent” setting, so you can set it to pretend it is like a desktop Safari. To do this, you tap on “…”
iOS Simulator Screen shot Jan 18, 2013 5.20.35 PM

Then tap “Set”.

Normally you should set it back to “Default User Agent” in case you experience any problems. Because “Web Explorer” is a mobile browser based mobile “Safari” engine. It does not support some desktop Safari functions.

How to fix iPhone 4S and iPhone 4 battery issue?

Recently some iPhone 4S users, and some iPhone 4 users who upgraded to iOS 5, experienced terrible battery drain. The causes of the battery drain may be different for different cases. Here is what I experienced.

My wife has an iPhone 4 bought August 2011. Recently my daughter upgraded my wife’s iPhone 4 with iOS 5 to use iTunes Match feature. I don’t remember since when, my wife started crying for the battery drain.
We try various adjustments to the settings and can not figure out why. Accidentally, I noticed her phone is doing the iTunes WiFi Sync when we come back home from outside. So I stop the auto sync feature. Since then, every full charge will work for a long time.

By the way, my iPhone 4S always works great!

Hope this may be helpful to you.

How many iPhones did Sprint activate in December 2011 quarter?

Apple Reports First Quarter Results
Information highlights:
The Company sold 37.04 million iPhones in the quarter.
International sales accounted for 58 percent of the quarter’s revenue.

Let start with the guess work:
1. Assume total domestic iPhone sales are 42% of total iPhone sales:
Total domestic iPhone sales = 0.42×37.04M = 15.56M
2. AT&T sold 7.6M
3. Verizon 4.2M

Therefore, Sprint and the other US carriers sold:
15.55M-11.8M = 3.75M

Since Sprint is the only major carrier other than AT&T and Verizon,
we can safely assume:
Sprint sold 3.75Mx0.75 = 2.81M
Minus or plus 0.5M

Therefore, Sprint should activate about 2.8M-3.0M iPhones in December quarter of 2011.
