Push Notifications Not Working on Unlocked iPhones

Push notifications will not work on your unlocked iphone. There is a problem with push which appeared few weeks ago when Apple released the iPhone OS 3.0 which included support for Push notifications. Weather the application is free or a paid version it will not work.

Keep in mind if you did not go through the process of unlocking your iPhone, which means you are still using AT&T as your carrier, you will not encounter this problem. I personally have not tested the push notifications personally yet but majority of the people using it on an unlocked phone said it either did not work or was not working correctly.

Will there be a solution? Probably not. Apple decided to sell the iPhone to AT&T and no other carrier. Therefore, this is not a problem Apple plans on resolving. Perhaps in the future if the iPhone is available on other carriers such as T-Mobile, then there might a possibility.

iPhone 3GS Web Speed Test

The iPhone web browser speed test knocks the competition out of the water. The statistics of the tests were rather astonishing. Medialets ran the SunSpider test suite with Safari 4.0.1 on a 2.0 GHz Intel Core 2 Duo White MacBook (the baseline for comparisons), Mobile Safari on the iPhone 3G with iPhone OS v2.2.1, Mobile Safari on the iPhone 3G with iPhone OS v3.0, Mobile Safari on the iPhone 3GS with iPhone OS v3.0, the "Browser" app on the T-Mobile G1 with Android OS v1.5 (Cupcake) and the "Web" app on the Palm Pre with Web OS v1.0.2.

iPhone OS 3.0 on the same iPhone 3G yields nearly 3X the JavaScript performance in Mobile Safari vs. using iPhone OS 2.2.1. Which should make everyone who has not bought a 3GS very happy. The iPhone 3GS steps up another factor of 3, bringing JavaScript performance on the iPhone 3GS to 12X that of a desktop machine that has well over four times the raw processing power.

The T-Mobile G1 running the "Cupcake" version of the Android OS finished the test suite in about 91 seconds. It is about a third faster than the iPhone 3G running Apple's OS (2.2.1). The Palm Pre had speeds that closely rival the iPhone 3G running Apple's OS 3.0.

Google Android 1.5 code name Cupcake released May 11 2009

T-Mobile G1 users will be getting an OTA (over-the-air) upgrade to the Android 1.5 "Cupcake" which is being pushed by T-Mobile randomly this month. Some of the features that are coming with the upgrade should have been there on the initial release and have been far pass due.

Some of the new features include an on-screen QWERTY keyboard (which helps prepare for the next Google phone which rumors say will be released this summer as the T-Mobile myTouch 3G). Other enhancements on the Cupcake include direct photo upload to Picasa and video upload to YouTube with the option to make them public or private. The picture or recorded video can also be sent as MMS and type in a title or caption.  Faster browser thanks to the new JavaScript and webkit engines.

A new radio has been added on this release which should help the battery life as well. A few things that were not mentioned on the release also include contacts photo appearing next to the contacts name, home screen widgets, voice search, and of course a call log that makes sense. The Android 1.0 told you how long ago the last call was made but not what time. The Android 1.5 displays what time the last call was made (this feature should have been available on the 1.0 release).

T-Mobile Goes 3G

T-Mobile has quite a few things up their sleeves right now.
First off, T-Mobile finally unleashes their 3G Network. It was available for testing purposes in New York but now will be available in the major cities in U.S.

Let's get a quick breakdown of the most commonly used networks by your provider:
note: Kbps stands for Kilobytes per second.

Edge: Enhanced Data rates for GSM Evolution (or Enhanced Data GSM Environment)
Edge Speed: Ideally 200 Kbps, realisticly its closer to 90 Kbps

GPRS: General Packet Radio Service (an upgrade from GSM network). This is 2.5G that gives the speed between 30Kbps - 50Kbps

UMTS: Universal Mobile Telephone Service. This is the 3G Service provided by T-Mobile and ATT. This service is aimed to provide up to 2Mbps but in the real world, you'll see 300Kpbs - 400Kbps (which is still an amazing speed compared to Edge or GPRS).
