Is there a quick way to make the Treo return to the home network after it's roaming? For example, when I use the elevator in my building my phone starts roaming (blue triangle). When I get into my apartment it stays roaming for any length of time before randomly switching back to Sprint. In my apartment I can get full Sprint signal without a problem, but the phone just doesn't switch back over. The same thing happens in other locations. Other than turning the phone off and back on is there a way to make it switch back, or "refresh" the network?

Any ideas? The reason for not using the roaming network is due to data speeds and also sometimes call seem to divert to voicemail when roaming.
