On the first day on the Apple iPhone 3GS went on sale was the biggest day of sales for all of AT & T, according to an internal memo sent to employees of companies that have already been published in various blogs.

iPhone 3G S buyers there is still a delay in activation of its new smart phones, but apparently, Apple wants to make it up to them.

Apple began notifying affected customers via email on Sunday that they might be further delayed for another two days because of “system issues” and “high activation volumes,” according to readers of various blogs who claim to have received e-mail message.

The problems began immediately after the launch of new iPhone on Friday.

As a way of apology for the delay, the same e-mail, said Apple plans to offer customers a $ 30 credit at the iTunes Store Credit “inconvenience this delay has resulted.”

Here is the full text of the e-mail:

Dear Apple Customer,

Thank you for your recent Apple Store order. We appreciate your patience and apologize for any inconvenience caused by the delay in activating your iPhone.

We are still addressing the issue, which had been encountered in the process of activating your iPhone, at least, and T. Unfortunately, because of the system and still high levels of activation, it may take us up to 48 additional hours.

On Monday, you’ll receive an email from the Apple iTunes Store with a credit of $ 30. We hope you enjoy this gift, and please accept our sincere apologies for any inconvenience this delay has caused.

Thank you for choosing Apple.

Best regards,
Apple Online Store Team

Apple representatives did not immediately respond to requests for comment.

In July last year in the iPhone, as the launch of new customers trying to fill needed at the store activation process overwhelmed AT & T activation servers slowed Apple Store scanning lines, and eventually crashed the servers at all. Apple ditched soon in store activation and a “unbricking” phones that allow customers include them in the house, rather than stand on line because of crashed servers.

Contrasts sharply with the frenzied first day of the sale of the original iPhone, and last year’s iPhone 3G, launched on Friday was significantly smaller and quieter than the crowd for smartphone debut.

One analyst expected Apple to sell 500,000 iPhones this weekend. This is half the phones, as Apple has sold when he began to iPhone 3G, Apple has sold but that the phone in 21 countries, on the first day. For comparison, iPhone 3G S was sold in eight countries, on his first day.

AT & T is upgrading its network and use the 850MHz spectrum of beef its wireless 3G, which should help alleviate the dropped calls and slow network connections for the iPhone 3G and iPhone 3G S users.

Apple said this week that it sold over a million iPhone 3G in the model around the world late last week after the phone went on sale on Friday. Exactly how many of these phones have been activated on AT & T network in the United States is not yet known, but in addition to more intensive data iPhones, likely to put additional strain on the network carrier.

Nonetheless, AT & T representative Mark Siegel said Gearlog blog on Tuesday that the company is ready for onslaught of new users of iPhone. One of the things he was doing to prepare upgrading their networks, so that it can offer wireless 3G services with the use of its 850MHz spectrum licenses. For the most part, AT & T has been using the spectrum in the range 1900 MHz to deliver its services to 3G, which have become saturated, Gearlog explains. This means that, as AT & T sells more 3G devices, such as the iPhone, has been cramming more users in an increasingly crowded spectrum band.

This could explain why some users complained about dropped calls and slow Net connection using iPhone 3G, one question that CNET News said almost a year after, iPhone 3G was launched. This problem is especially acute in large cities such as New York and San Francisco where the bases are concentrated and where the iPhone users 1900MHz spectrum is dominant.

Siegel said that the upgrading of equipment will allow AT & T using its 850MHz spectrum for 3G services should help alleviate some of the problems of congestion. Since the 850MHz spectrum is at the lower boundary of the frequency range, it is able to travel long distances and penetrate walls more easily than signals on the 1900MHz band.

When asked about problems with dropped calls on iPhone 3G users a year ago, Siegel CNET News reported that the company is working to expand its share of 3G network, which operates on 850MHz band. He downplayed the need to add 850MHz spectrum for 3G services, saying that it “does not mean that you can not get a good experience on 1900MHz.”

Now, Siegel believes that the addition of 850MHz make a big improvement, according to Gearlog stories.

“At 850, when he turned in some markets, people have noticed a great difference,” he was quoted as saying.

Apart from adding 850MHz 3G services, AT & T also other improvements in its network, such as an upgrade to the next iteration of technology, HSDPA, which is expected to double download speeds from AT & T network.

Apple on Friday upped its stake in British chip company, Imagination Technologies.

The Company acquired 2.2 million shares at 1.43 pounds ($ 2.36), amounting to a total of 3.14 million pounds ($ 5.19 million). Purchase brings Apple shares in the company to 9.5 percent, effectively tripling its holdings in the imagination, according to a report on MocoNews.

Apple uses in the Imagination SGX GPU in the recently released iPhone 3G S, which allows you to have more graphics using Apple in the OpenGL ES 2.0, according to AppleInsider. Samsung, Imagination reported integration of technology into the system-on-on-chip devices.

OpenGL ES 2.0 is a cross-platform API, which allows for 2D and 3D graphics on embedded systems. In essence, this creates a low-level interface between software and graphics hardware systems.
