GSM Network refresher

[dutchguy]

Hi, I am looking for a program that refreshes the GSM network automatically. I have a T-Mobile MDA III, but it has a problem: sometimes when I do not use the phone for a while (a day or so), I cannot be called, but when I call myself or refresh the GSM network, I can be called.

If someone could make a program (maybe something already exists?) that refreshes the GSM network each hour or so, that would be great.

or just upgrade to a newer radio rom and those problems are over...

That would be nice, but I'm already using the latest rom (02.98.90).

What do you mean by refresh? Going into flightmode and immediate return? There are already a lot of event driven software... most probably even one offers right that.

Yes, going to flightmode and back would probably be enough. The problem would be that I would have to reenter my pincode (or the program would have to do that too). Which program could do that (each hour or so)?
