Apple is already providing developers with a new iPhone firmware beta with enhanced location-finding that could lead to true navigation as well as the roots for background push services.
The one of new features is update to core Location - it can now recognize the cardinal direction of an iPhone with GPS as well as its velocity, both of which are ingredients necessary to providing turn-by-turn directions. The additions confirm statements recently by Apple's Greg Joswiak, who rejected earlier claims that iPhone 3G's GPS antenna wasn't powerful enough to handle navigation and in turn explained that "complicated issues" are holding the device back from serving as a true navigation unit.
Apple is also implementing a rough version of its background push notification service in the 2.1 firmware. Announced at the Worldwide Developers Conference, the feature lets third-party native programs receive data such as alerts or new messages without actively running. The measure saves processing power without interrupting some apps that depend on constant access to the Internet.
The inclusion of this early version of the code alludes to the 2.1 update becoming public at the same time as the push notification service itself, which is tentatively due for September. In the meantime, Apple and its US partner AT&T are known to be testing iPhone 2.0.1, a maintenance release that likely fixes some of the outstanding bugs with the initial 2.0 release.
Being a suite of command-line utilities, this release is meant primarily for developers. While you can certainly jailbreak (both 3G and first-gen) and unlock (first-gen) with it, it's not really something you want to try without reading the lengthy, detailed README. If you don't have the patience to do that, this release is not for you.
For users this news mean that quite soon there will be a new version of winpwn, supporting 2.0.
There is not much defference between Safari 1.1.4 and 2.0. But Under the hood, MobileSafari 2.0's performance is hugely improved over 1.1.4. Everything related to web surfing feels faster, web pages consistently load faster on 2.0, both via Wi-Fi and EDGE. This has nothing to do with the new iPhone 3G hardware — this is about dramatic performance improvements on original iPhones upgraded to the 2.0 OS.
In August last year,
|Test||1.0.1||1.1.4||2.0||Vs. 1.0.1 / 1.1.4|
|100,000 iterations||3.209||1.096||0.145||22× / 8×|
|10,000 divisions||0.413||0.181||0.029||14× / 6×|
|10,000 sin(x) calls||0.709||0.373||0.140||5× / 3×|
|10,000 string allocations||0.777||0.434||0.133||6× / 3×|
|10,000 function calls||0.904||0.595||0.115||8× / 5×|
The last column shows how many times faster the 2.0 version of MobileSafari was versus 1.0.1 and 1.1.4. The same results, charted (smaller bars are faster) can be viewed above.
For all the hubbub regarding the new App Store, most “iPhone software” runs in the web browser. But improvements in WebKit performance often help native iPhone app performance, too — a slew of my favorite native iPhone apps have built-in WebKit browsers (e.g., NetNewsWire, Twitterrific, Instapaper, and Cocktails). When WebKit performance improves, any app that uses WebKit improves, and WebKit improved a lot between iPhone 1.1.4 and 2.0.0.
The battery life on Apple's new 3G iPhone isn't great, but it beats that of other 3G smartphones we've seen, say testers at PC World's Test Center. In the study's standard talk-time battery life test, an iPhone, on average, ran 5 hours and 38 minutes, a performance PC World deems "fair."
The original iPhone, which ran on AT&T's slower EDGE network, lasted 10 hours of our test. But the 3G iPhone beat out the rest of the current 3G smartphone pack, most of which fell shy of the five-hour mark that's the cutoff between a word score of fair and poor in PC World's performance ratings.
The iPhone 3G also beat out competitors on Sprint and Verizon's EVDO mobile broadband networks, including the Palm Centro (4:19) and the Samsung Instinct (5:33), PC World says.

JamVM is a new Java Virtual Machine which conforms to the JVM specification version 2 (blue book). In comparison to most other VM's (free and commercial) it is extremely small, with a stripped executable on PowerPC of only ~200K, and Intel 180K. However, unlike other small VMs (e.g. KVM) it is designed to support the full specification, and includes support for object finalisation, Soft/Weak/Phantom References, class-unloading, the Java Native Interface (JNI) and the Reflection API.JamVM currently only includes an interpreter (keeps it small). However, the interpreter is highly optimised, and performance is on par with a simple JIT. As most of the code is written in C it is easy to port to new architectures.
