When it comes to the iPhone, it’s really really difficult to narrow my app love down to just three picks. So with apologies in advance for all those amazing applications that didn’t make this cut, let me jump in with three choices that I simply do not live without on my (jailbroken) iPhone:

Cydia. When Jay Freeman’s Cydia first debuted, I was hesitant to use it. It sucked up the root partition space like a sponge and its interface was, at best, preliminary. And now, in 2.0, Cydia owns me. It’s simply fabulous. From its command-line Unix support to its fully overhauled interface to its extremely workable update system, Cydia provides a powerful software distribution system, perfect for modern smartphones and a great competitor to AppStore.

Boss Prefs. Boss Prefs offers a wonderful services application. It lets me enable and disable services such as EDGE, Bluetooth and SSH from a central application. Because I only intermittently subscribe to data plans, Boss Prefs ensures that I won’t accidentally start downloading a la carte data that starts at about $500 million (or so) per kilobyte. It also lets me enable and disable my mail accounts, so the iPhone works perfectly for whichever mode I’m in: intrepid TUAW blogger at large or private Soccer Mom on the go.

Just in time for the first really scary hurricane of the season, Weather Underground is providing an iPhone-specific version of their mobile site that includes a tropical storm tracker. The mobile site URL is http://i.wund.com, and the tropical storm page can be accessed directly at http://i.wund.com/tropical.

As you can see in the screenshot above, the tracker shows the location, intensity, and other statistical information about each storm. In this case we’re looking at Tropical Storm Gustav, which appears to now be a Category 3 hurricane. The full-screen view seen above requires a flip to landscape mode.

I’ll skip the obligatory mini-biography of Guy and cut to the chase: the dude gets a whopping 36 hours of standby time with his iPhone 3G. True, many other phones get better battery life and can go for days without a charge. But anyone banging their iPhone on the wall, wishing the darn thing didn’t suck down the juice like a preschooler in the Sahara will appreciate his detailed account of the settings used to eke out legnthy iPhone standby time.

Last week, there was a story stating that Orange had hired actors to pad iPhone lineups for the Polish debut. This week, they’re denying it.

According to Orange, some of their employees were joining customers in line to share in the excitement and talk about the product, not pose as potential customers. “Their aim is to welcome people to the Orange shop, share in their excitement and give information about Orange tariffs,” a spokeswoman told Ad Age.

Of course, if these people were on the clock, then technically they were paid to stand in line. But now we’re just splitting hairs. The original story identified fear of slow sales as Orange’s motivation, but they’re reporting that sales have been good in Poland.
