Twitter today pushed back a change to its service that will prevent third-party applications from offering notifications to their users. The services that Talon, Tweetbot, Tweetings, and Twitterrific depend on will still be shut down. It just won’t happen when originally planned.

The replacement Twitter is working on might be completely unsuited for the needs of these third-party developers. And deliberately so. They’re trying to get the company to change course.

July 20, 2007: Just a month after the original iPhone goes on sale, the first app gets compiled and launched for the new platform.

Called “Hello World,” the software serves more as a proof of concept than a serious tool. But it demonstrates that third-party apps will become a cornerstone of the new iPhone economy. It’s a shame Apple doesn’t get the memo.

For longer than I have allowed myself to believe, the iPhone has been called a scanner that fits in your pocket. But if I wanted a high-quality copy of an old photograph, I still sought out a flatbed scanner, presuming the results would be superior to taking a picture of a picture with a phone.

Mainland China is Apple’s second biggest market, and will one day be its first. The company is making a big push on the mainland, opening new stores and investing in home-grown companies. Why the interest? Because China is the new Japan — it’s where the future is happening. All this week we take a look at the cutting-edge apps that define mobile life on the mainland.

SHANGHAI CITY, China — Just like their U.S. counterparts, Chinese youth obsess over their smartphones. But while the phones they use look the same, the apps are quite different: China has its own must-have apps that keep users’ eyes glued to screens at all hours of the day.

Some Chinese apps seem quite similar to their Western counterparts, but others boast innovative and intriguing features. Apple’s clearly interested: While slowing growth in China put a dent in APPL stock, Cupertino recently made a strategic $1 billion investment in Chinese Uber rival Didi Chuxing.

What other apps in China might grab Apple’s attention? Tim Cook could start his due diligence with this list of powerhouse Chinese iPhone apps. The country’s young people use these apps to listen to music, make purchases, get around town, interact with others and maintain their online identities.

These Chinese apps are impressive and convenient, and they are showing us the future of mobile: a world where everything is at our fingertips.
