...now it fully supports the Huawai E220.
Finally CradlePoint updated the firmware for their mobile access point PHS300 that bridges your GPRS/UMTS/HSDPA USB device to wireless lan. The PHS300 supported the E220 already but it was not as nice as it could have been. Now it works like a charm. I can have my E220 plugged into the PHS and just need to flick the switch to have Internet access a couple of seconds later. Some other features they added are: support for a SIM pin and display of the GSM signal strength.
After this firmware upgrade the PHS300 is a really good piece of hardware that was totally worth the money.
