The only way for me to check my company email is to dial into our servers. Trouble is, my wireless modem software suddenly got jumbled: when I tell it to check for emails, the software fires up, but eventually times out, and only then places the call. I've tried several soft and hard resets, no luck. I have MZ 1.0.44 and SZ 1.0.29.

Is there some way to reload the firmware without running the gauntlet of visiting the phone store five times until I find someone who knows how to plug my phone into their PC?
