While the company says the included data should be good enough for emails,
social network status updates, and even streaming music, it's not
particularly fast: just 128 kilobytes per second on average, chief marketing

128Kbps的话,那也就是介于edge(~200Kbps)和GPRS(~30Kbps)之间,或者勉强算edge
也就是2.75G. |

i believe The switching refers to natural evolution path being supported from
standardbody/vendors for the air interface. GSM->GPRS->EDGE->HSPDA->UMTS/WCDMA
Follow the path ofcoz means easier migration compared to swapping a
CDMA2000 basestation to WCDMA base station |

发帖数: 16 | 18 a chinese company charged PNY over flashdisk, the Fortune call this man-bite-
dog,heng. If they really has the patent, they should greedily charge all the
flashdisk manufactuers in US, like what happen to RIMM.
as to 3G, the integration of 2G and 3G is quite complicate (GSM/GPRS/EDGE/
WCDMA)), considering the huge effect and limited service advantage comparing
to 2G,and the wimax stuff. the adoption of 3G is much longer.

You can turn your smartphone into a portable hotspot. The Internet
connection link is the GPRS/3G/4G data service, and the WiFi part of the
tethering smartphone works like an 802.11 access point. |

发帖数: 204 | 25 要把老婆加到我的family plan里，看上一款很满意的NOKIA Nuron 5230（我一直用
Nokia）。所以很少考虑别的牌子。因为是t-mobile用户，iphone自然与我无缘,况且也
没指着它上网，毕竟不是商务人士。之前一直看好Google G1，但是还每月要多花30刀
的上网费。
最后看到这个Nuron 5230，touch screen，不知道是不是Nokia第一个。整体感觉不错
。但是有几个问题要请教大家
1. Symbian 9.4 S60 5.0（S60第五版）的系统。我如果假期回国需要中文支持的话怎
么办啊，只要能收发中文短信就行。
2. 自带的GPS很吸引我！Nokia自己的Ovi地图系统，用的时候收不收钱啊？应该不走
GPRS流量的吧，是不是和普通的Garmin什么的一样用的时候不另外收费呢
谢谢大家，问题很白痴，期待耐心详尽的解释。如果对这款机子有什么建议也欢迎提出

发帖数: 1551 | 26 第一个问题 可以到 dospy上看看有没有中文的解决方案，一般来说nokia的智能手机都
可以通过刷rom，或是安装字体来解决
自带的gps比较弱，如果没有gprs的话，定位可能相当慢。nokia的ovi地图不收钱。 |

发帖数: 10 | 29 Dear brothers and sisters,
Would you please tell me how can I connect my cell phone to my laptop to get
internet access? I am currently using Tmobile T-zone without internet plan. My
phone is Motorolla V66. When I connect it to my laptop using a data cable, it
shows a 115.6KB connection and can send some and receive some data through
GPRS service, but it never connects to any website. Do I have to pay $19.99 to
get internet access from T-mobile? Could you tell me what's the problem?
Thanks. |
