I have a BlackBerry 7100i that keeps sending the e-mail saying my handheld has been registered with the network on about an hourly basis. I contacted BlackBerry support and they couldn't figure anything out other than to suggest doing a hard reset which doesn't do anything. Has anyone else experienced this problem before and did you get it solved? Any help to fix this problem as it disrupts my e-mails and text messages being received to my phone would be greatly appreciated.
