Updating huawei e220

The E220 antenna is internal; the USB cable does not act as an antenna.The external antenna connector is not accessible without opening the device (voiding any warranty).Huawei's Dashboard and updates for it are also available from Huawei's website, or the 11.3.01 firmware for 7.2 Mbit/s from Net Com (in reality 'flashing' this device means writing a firmware image to its internal flash memory, which is different from "updating the dashboard", which is simply writing a new CDFS disc image to the USB mass storage device that appears in the operating system).Flashing the firmware of this device doesn't change the USB Mass Storage memory used for the operator's software, therefore connection settings (such as APN) will be retained.

Huawei have released new firmware to the operators, who have generally made it available on their websites.Some network operators selling the E220, however, replace Huawei's software with their own, which often is software-locked (albeit not SIM-locked) to work only with the operator's own network.End-users can use also third-party open source software Py Humod or freeware MWconn.Launched on 21 June 2006, the device is used for wireless Internet access using 3.5G, 3G, or 2G mobile telephony networks.It supports UMTS (including HSDPA), EDGE, GPRS and GSM.
