UBM TechInsights got its hands on a new iPhone 4S when they hit stores Friday (Oct. 14) and immediately began a preliminary teardown analysis.
What did we find? How does the iPhone 4S differ from the original iPhone 4 released in the summer of 2010? First, is the design of a singular handset that will work across multiple carrier platforms such as GSM and CDMA. This was not a surprise, as such a capability was evident in the Verizon version of the iPhone 4. That version incorporated the first use of Qualcomm’s MDM6600—a chipset that was already capable of working across both GSM and CDMA mobile standards.
The foundation for a “world phone” was set, and UBM TechInsights' discovery of a Qualcomm MDM6610 confirmed our initial speculation that the Verizon iPhone 4 was precursor for this design change. Not only that, but it finalizes Apple’s baseband supplier switch from Infineon to Qualcomm. Qualcomm was able to secure not only the design win of the MDM6610, but also the RTR8605 RF transceiver and their PM8028 power management device.
Another major winner is Broadcom. Not only did Broadcom maintain their socket from the iPhone 4, they convinced Apple to upgrade to one of their newer devices, the BCM4330 802.11n WiFi/Bluetooth/FM Radio chipset. This is the second major design win for Broadcom who saw the same IC incorporated in the popular Samsung Galaxy S II handset. Cirrus Logic and Dialog Semiconductor also found their companies’ products upgraded within the iPhone 4S. Apple selected the CLI1560B0 audio codec, moving from the CLI1495 that was in the iPhone 4. Apple also upgraded to Dialog’s D1881A power management IC, moving from the D1815A in the previous handset.
The second biggest change from the iPhone 4 to the iPhone 4S is one that was telegraphed on the release of the iPad 2. The selection of the Apple A5 dual-core processor should come as no surprise to anyone familiar with Apple’s tendency to use their tablet format as a precursor to a new processor. As the iPad’s use of the A4 processor alluded to its use in the iPhone 4, the iPad 2 and the introduction of the A5 processor within its casing foretold its use in the iPhone 4S.

I spoke to a friend of mine. He told me that he saw Apple 4 phones in China with native Apple apps installed on them. Around $50. Wonder if this can be true. I know that there are clones around with a cranky software (Windoze or so) on them, but this was new for me. Is it a rumor or can this be true?
And if true, what the heck can we do about this? These Chinese copy (thus steal) almost everything. Quite worrying!
And where exactly will the Chinese get the A6 chip? You think Apple will sell it to them? if you change some of the components, it's not a 4S. Chinese copy phones may look the same, but they do not run apps...they are strictly for status, just like their fake Rolexes
Inside of iphone 4s is very clear. Many Chinese companies could copy its design.They only need change some components which could cut down the cost, then sell it with competitive price in the market. I personally think that the terminal selling quantity for apple phone could not surpass the copy manufacturers' in China. Actually, the brand of Apple is the key value. If not, it is the same as many other cellphone in China market.
Samsung and others copy Apple. It takes them at least a year or two to catch up. That's what makes Apple unique. Apple never seems to run out of new ideas that differentiate them from the me-tos. The only "good" idea Samsung ever had was to copy American and Japanese companies for their products.
As it says on page 2, Qualcomm RTR8605 multimode RF transceiver, which goes with the Qualcomm MDM6610 baseband.
The article indicates the Qualcomm baseband was already used in iPhone 4, but i think the RF may have kicked out an Intel/Infineon peice of RF
great set of design people created this piece. But it seems Samsung supplied A5 processor. He is trying to compete Apple. Who will be the winner?How apple has the mind set to buy an ic fom his competitor?great people and community.it is good.

We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
