A firmware update is available for the Huawei E5, aka the iMo, also known as the E5830 / E5832.
The update is a self-contained executable that needs to be run on a Windows host, and is only intended for unlocked units. Compatibility with network-branded equipment is not guaranteed.

The update can be downloaded from the FTP site here - ftp://ftpaccess:Brightpoint1@ftp.brightpointuk.co.uk/Technical%20Support...

Key Features

The E5832 is a very handy little device indeed - one of the first battery-powered 3G wireless routers on the market.
Taking a SIM card and providing 3G data service at up to 7.2Mbps, the device is also a WiFi access point, meaning that you can share the 3G connection between multiple WiFi enabled clients. Whilst these devices have been available for a while now, this device is battery-powered and measures only 93mm x 48mm!
