eWeek reports: "Teardowns of the Verizon Wireless iPhone 4 by repair site iFixit and analyst
firm IHS iSuppli revealed that, while on the surface they appeared largely identical, Apple has
 done quite a bit of work on a phone that, in a matter of months, is 'set to be antiquated by the
 iPhone 5,' iFixit’s Kyle Wein wrote in a Feb. 7 report. Apple made changes to the phone’s
 battery and vibrator, but most important are new design choices regarding the
 Verizon iPhone’s CDMA technology and antenna, and the switch from a
 Broadcom chip to a Qualcomm MDM chipset.
Such changes, wrote iSuppli senior analyst Wayne Lam, in a report the same day, 'likely foretell of future updates coming in the next major model release of the Apple iPhone later this year.'"
