When I lost my signal on my BlackBerry, or just when the edge indicator is not in capital letters (edge not EDGE), I usually just go to "Manage Connections", then I disable "Mobile Network" (which took about 10 seconds), then I turn it on again. To make this step easier (and I don't have to stare at my screen for 10 seconds), I made this small program to quickly restart the mobile network connection.
Several people have requested that I made an app that can switch from 2G to 3G (or the other way around). Unfortunately this is not possible with the current API.
This app is free If you have any question, you can send it to email@example.com.
