In this post I was asked a question about the reception quality of the Vodafone v1605. When I first got hold of the v1605 to test it was something I made a note of.
In fact the radio stack has been problems with most of the devices that HTC bring out in the Pocket PC, the v1640 was a REAL problem for reception until Vodafone brought out an update (here)...
Well as it's taking what seems like an age to bring out updates for these devices I feel it's my duty to pass you the details I've found to upgrade your Radio stack...
This link, that takes you to a site run by Mr Vanx, will give you a step by step guide on how to do such a thing... But beware that this can brick your device! You have been warned... It's worth it though...
