这个情况下VZ的IPHONE选用QCOM还是很自然的。我倒是希望AAPL把INTC的baseband踢掉

Dev Team 传出来的消息应该不会假
In a reply to a tweet, MuscleNerd of iPhone Dev Team has confirmed that
iOS 4 (formerly iPhone OS 4) is confirmed to be unlockable, and probably
so is the yet to be released iPhone 4. What they have actually got this
time around is a new exploit for the latest 05.12.01 / 05.13.04 basebands,
which they have been saving for months for a major new update – the time
for which has now come. |

发帖数: 11116 | 21 unlock是指解锁baseband（5.13.04这个东西，os4也是这个baseband），这个
ultrasn0w 0.93出的时候就已经是通解了，问题ip4现在还没办法jb（破），就是说没办法装这个ultrasn0w上去，ip4不行，3gs升了os4也不行，只有3g可以。
我的理解是这样的
英文也是jb+unlock两个词，当然一般unlock的前提必须是能jb，有时候就不用说了。 |

这几年手机行业真是市场巨变的SEA CHANGE。在苹果手机轰轰烈烈的成功中其他很多厂商一下子败得就快消失了。三四年前NOK股价四五十块钱，现在四五块钱，RIMM股价当时一百多块钱，现在十几块钱，这两个公司都跌成前几年的十分之一。当时就勉强求存的PALM先被收购，接着上演了一出差不多白送产品的大戏，现在从产品到软件都正式消失和开源了。另一方面，苹果和三星现在占据了整个手机行业总利润的几乎全部，看到过不同的报道，但都是苹果差不多百分之八十上下，三星剩下的十几二十，其他厂商加起来拿到了个位数的全球手机利润百分比。AMAZING！其中三星的成功除了因为被苹果选中成为多项产品供应商得以在其中窥取苹果的产品设计和创意，所以模仿得最像苹果产品，而且他们从苹果本身的产品销售中得到巨额配件利润。另外就是谷歌的ANDROID，其实提供了最大帮助的就是对三星。三星本来在蓝莓和N95统治智能手机的年代在SMART PHONE上的全球占有率是百分之个位数，借助ANDROID和对苹果产品创意的窥取模仿，三星现在的市占率是当时的几十倍。在此... 阅读全帖 |
