Upgrade 3,6 to 7,2 Huawei Modem E 220

I've just got my mits on the latest firmware for the Vodafone Huawei E220. This update upgrades the modem to download at speeds up to 7.2Mbps - compared to the standard 3.6Mbps. I've just installed it and run a speed test in a 7.2Mbps area and I'm getting average speeds of around 2.5Mbps, peaking at 4.3Mbps (see the NetPerSec screenshot). The lack of receive diversity on the device will prevent it from hitting speeds much higher than this.  The usual disclaimers apply here - if you want to install the update do so at your own risk.

To make use of the unlock code, insert an unauthorized sim card to your Huawei modem. Unauthorized sim card meaning sim card from any operators other than the one the modem is currently locked to.

I have tested it on my E1762 and it worked perfectly.

iPad 2 announcement

A lot of people have noticed that the calendar app of iPad 2 has the digit “9” printed on it. And this has got everyone thinking that the announcement on iPad 2 is due on February 9, 2011. Actually the calendar app of the first version of iPad had “27” written on it and the announcement of the same was made on January 27.
The other coincidence is that has got the people thinking is the calendar app date of the iPhone 4 and the fact that the original iPad was announced on a Wednesday as well. No wonder people are waiting for February 9 with bated breath.

Apple releases the white iPhone 4

The white iPhone 4 has been promised by Apple for almost a year — today it officially arrived.
Apple said the white iPhone 4 would be available tomorrow at Apple’s retail stores, AT&T and Verizon Wireless stores and select Apple Authorized Resellers. The white iPhone 4 will be available for $199 for the 16GB model and $299 for the 32GB model with a new two year agreement.

The white iPhone has been spotted over the past few days in Europe, where it apparently went on sale a bit earlier than expected. Some customers in the UK and Belgium where able to get their hands on the devices, according to Mac Rumors.

“The white iPhone 4 has finally arrived and it’s beautiful,” said Philip Schiller, Apple’s senior vice president of Worldwide Product Marketing. “We appreciate everyone who has waited patiently while we’ve worked to get every detail right.”
Apple has never given a reason for the delay of the white iPhone 4, other than it has “proven more challenging to manufacture than expected.” Originally scheduled to be released shortly after the black iPhone, the white iPhone 4 was delayed in late July until later in 2010, and again in October until spring 2011.
